In separate speeches on Monday, both Home Secretary Theresa May and senior Metropolitan Police officials said the terror threat posed by jihadists who have returned to Britain from Iraq and Syria is the most serious the nation has ever faced.
Comment: Call it blowback from NATO's own terrorist activity. But the threat of terrorism is required to keep the wars going.
Speaking to MPs, May warned Britain faces the most serious threat to its security from prospective terrorists since before or after the September 11 attacks on the US in 2001.
Possible terror attacks could manifest as a 'lone wolf' beheading in a public street or crowded shopping center - or as a crude, homemade bomb made from fertilizer.
Comment: Interesting scenarios. Could practice drills be in the planning?
These most recent warnings echo the cautionary words of top security personnel, who earlier this month told parliament the state's levels of terrorist activity are so acute that a terror attack in the near future is almost certain.
Comment: If the increased security measures fail to be as strong as the powers-that-be want them, you can be sure there will be a "terrorist attack" to hammer home why these security measures are needed.
