There is, it seems, something new under the sun.

Geopolitically speaking, when it comes to war and the imperial principle, we may be in uncharted territory. Take a look around and you'll see a world at the boiling point. From Ukraine to Syria, South Sudan to Thailand, Libya to Bosnia, Turkey to Venezuela, citizen protest (left and right) is sparking not just disorganization, but what looks like, to coin a word, de-organization at a global level. Increasingly, the unitary status of states, large and small, old and new, is being called into question. Civil war, violence, and internecine struggles of various sorts are visibly on the rise. In many cases, outside countries are involved and yet in each instance state power seems to be draining away to no other state's gain. So here's one question: Where exactly is power located on this planet of ours right now?

There is, of course, a single waning superpower that has in this new century sent its military into action globally, aggressively, repeatedly -- and disastrously. And yet these actions have failed to reinforce the imperial system of organizing and garrisoning the planet that it put in place at the end of World War II; nor has it proven capable of organizing a new global system for a new century. In fact, everywhere it's touched militarily, local and regional chaos have followed.

In the meantime, its own political system has grown gargantuan and unwieldy; its electoral process has been overwhelmed by vast flows of money from the wealthy 1%; and its governing system is visibly troubled, if not dysfunctional. Its rich are ever richer, its poor ever poorer, and its middle class in decline. Its military, the largest by many multiples on the planet, is nonetheless beginning to cut back. Around the world, allies, client states, and enemies are paying ever less attention to its wishes and desires, often without serious penalty. It has the classic look of a great power in decline and in another moment it might be easy enough to predict that, though far wealthier than its Cold War superpower adversary, it has simply been heading for the graveyard more slowly but no less surely.

Such a prediction would, however, be unwise. Never since the modern era began has a waning power so lacked serious competition or been essentially without enemies. Whether in decline or not, the United States -- these days being hailed as "the new Saudi Arabia" in terms of its frackable energy wealth -- is visibly in no danger of losing its status as the planet's only imperial power.

What, then, of power itself? Are we still in some strange way -- to bring back the long forgotten Bush-era phrase -- in a unipolar moment? Or is power, as it was briefly fashionable to say, increasingly multipolar? Or is it helter-skelter-polar? Or on a planet whose temperatures are rising, droughts growing more severe, and future food prices threatening to soar (meaning yet more protest, violence, and disruption), are there even "poles" any more?

Russian Prime Minister Dmitry Medvedev said on Sunday that Ukraine's leaders had seized power illegally, and predicted their rule would end with "a new revolution [and] new bloodshed."

Medvedev said that, while Viktor Yanukovych had practically no authority, he remained the legitimate head of state according the constitution, adding: "If he is guilty before Ukraine - hold an impeachment procedure ... and try him."

"Everything else is lawlessness. The seizure of power," Medvedev said on his Facebook page. "And that means such order will be extremely unstable. It will end in a new revolution. New bloodshed."

The remarks were part of a series of Russian statements attacking the legitimacy of the pro-Western government that has been formed since Yanukovych fled Kiev more than a week ago. He surfaced on Friday in Russia.

Israeli special forces have raided a prison in central Israel after an inmate stole a gun, shot several guards and barricaded himself inside the compound, killing the notorious prisoner who was serving time for a gruesome murder carried out in the US.

Police identified the inmate as Samuel Sheinbein, an American who fled to Israel after murdering and dismembering another man in Maryland in 1997 and whose case sparked a high-profile row between the two allies.

Police special forces rushed to the prison in central Israel after Sheinbein stole a weapon and shot three guards, wounding two of them seriously. He then barricaded himself inside the compound where a standoff ensued, with counter-terrorism units dispatched to the scene. The inmate then opened fire again, wounding three more guards, before the forces shot him dead, police spokesman Micky Rosenfeld said.

Hospital officials said one of the wounded guards was fighting for his life. Police and the Israel prison service have opened investigations into the incident. Sheinbein's lawyers told Israeli TV that their client was under duress and that the Israeli prison service has ignored their warnings.

President Barack Obama, issuing a veiled warning to Israeli Prime Minister Benjamin Netanyahu on the eve of talks, said in an interview published on Sunday it would be harder for Washington to defend Israel against efforts to isolate it internationally if U.S.-led Middle East peace talks fail.

Obama, speaking to Bloomberg View, also made clear that he would press Netanyahu to allow him the time needed to test Iran's willingness to curb its nuclear ambitions, despite the Israeli leader's deep skepticism of the West's diplomatic engagement with Tehran.

Responding to the interview, a senior Israeli cabinet minister said the Netanyahu government was serious about peace but would not be pressured into endangering the Jewish state.

Obama said the "the window is closing" for a peace deal between Israel and the Palestinians, and called on Netanyahu to "seize the moment" to help achieve a framework agreement that Secretary John Kerry is trying to forge to extend peace talks.

Obama said his message to Netanyahu in a White House meeting scheduled for Monday would be: "If not now, when? And if not you, Mr. Prime Minister, then who?"

Mt. Gox, once the dominant exchange for bitcoin trading, on Friday said more than $470 million of the virtual currency vanished from its digital coffers, kicking into high gear a search for the missing money by victims and cybersleuths.

Acting alone and in groups, the people stepped up their efforts after Mt. Gox filed for bankruptcy protection in Japan and confirmed rumors it had lost almost 750,000 of its customers' bitcoins, as well as roughly 100,000 of its own.

Mt. Gox Chief Executive Mark Karpelès said technical issues had opened the way for fraudulent withdrawals, though he didn't provide details.

"There was some weakness in the system, and the bitcoins have disappeared. I apologize for causing trouble," Mr. Karpelès said at a packed news conference at a Tokyo courthouse after the bankruptcy filing.

The disappearance underscores the risks of currencies that exist only online and aren't backed by a central bank. Mt. Gox wasn't overseen by national regulators, so there is no entity to step in and back investors' deposits.

With the west and the G7 nations unlikely to pursue military options in retaliation to Russian aggression to deploy troops in Crimea region of Ukraine, threats of economic sanctions is being talked up.

President Obama said that the US will take a series of steps, both economic and diplomatic, to isolate Russia. They have suspended trade and investment talks already.

The UK has equally talked up the potential for sanctions, with the potential for an agreement on the details of those sanctions could be reached at the end of the week in an emergency EU summit.

Yet still there remains a degree of ambiguity as to the form in which what those sanctions could take. The UK government wittingly leaked their initial thoughts on sanctions yesterday when a minister quite blatantly left documents on the cabinets view on sanctions in full view for the worlds media to photograph and analyse.

That document identified a preference for restricting travel and visa, as opposed to tougher economic sanctions. In essence, it showed a lack of appetite amidst the UK government for tough bargaining with Russia.

Yet the true cost of sanctions, if Russia is hit hard, could hurt the UK much more than people think.

Russian President Vladimir Putin offered a vigorous defense Tuesday of Russian intervention in Ukraine, saying the pro-Russian former government in Kiev was illegally overthrown and that the man he regards as Ukraine's legitimate president asked him for military help.

But he also asserted that the troops wearing unmarked uniforms in Crimea are local self-defense groups - not Russian forces, as observers on the scene have said.

Accusing the West of encouraging an "unconstitutional coup" in Ukraine, Vladimir Putin said that Moscow reserves the right to protect Russians there.

President Barack Obama will strike a firmly populist tone in his 2015 budget plan on Tuesday, proposing to pay for an expansion of a popular tax credit for the working poor by eliminating tax breaks claimed by wealthy Americans.

The proposal to expand one of the most popular U.S. government poverty reduction programs, the Earned Income Tax Credit, would cost $60 billion, a modest amount in a budget in which the president has $1.014 trillion in spending to parcel out, the White House said.

Obama would pay for the tax credit expansion by closing tax loopholes used typically by wealthy investors or employees of professional service companies such as law, consulting or lobbying firms.

Hugo Chavez's death radically shifted the balance of power in Latin America and the Caribbean but not for the reasons that you are being told on the mainstream media.

• Cameron's adviser Hugh Powell left file on display to photographers
• Document revealed Britain will not impose sanctions against Russia
• Will not support military action against the country either, it showed
• Also disclosed Russian investors will not be frozen out of City of London
• Hague and Cameron claimed today they would 'get tough' with Russia
• Britain will not impose sanctions or support military action against Russia, according to a briefing paper that was revealed in error yesterday.

The document became public when one of David Cameron's advisers left it on display to press photographers before a Downing Street meeting.

The blunder by Hugh Powell, who is deputy national security adviser, also shows that the Government has no plans to freeze Russian investors out of the City of London.

Instead, the briefing paper recommends that the UN should take the lead and possibly send monitors to Ukraine.

The document says: 'UK should not support for now, trade sanctions ... or close London's financial centre to Russians.'
