US intelligence officials say they are concerned al-Qaeda is trying to develop a new and sophisticated bomb that could go undetected through airport security.
On Wednesday, the Department of Homeland Security ordered the enhancement of security measures at selected overseas airports with nonstop flights to the US.
"The warnings are coming right on the eve of the 4th of July holiday, this patriotic holiday in the United States," said Daniel Patrick Welch in a phone interview with Press TV.
"The American people are exhausted from this constant terrorist warnings and the warning of the next great 9/11," he added.
The news just shows "how disastrous and wrong-headed the US policy has become or has always been actually," Welch said.
"In erecting this massive security state," he pointed out, "the only thing they have managed to foil so far are the plots that they themselves have concocted."
"They have caught people that they have enticed into a trap and caught them before they acted."
The analyst said that the security threats represent a foreign policy blowback resulting from US wars and interventions.
"If you keep funding the same organizations in Iraq and Syria and all over the world eventually the genie is going to come back and bite you."
"It [warning] could be a false flag or it could the obvious result of wrong-headed policy. It really doesn't make much of a difference to people flying," Welch said.
The authorities seek to keep the population "scared and subservient to the people in power," he concluded.
I don't see these so-called "terrorists" getting in boats to attack America or cross over from Mexico. The U.S. government will keep tabs on them and direct them accordingly.
