The greatest threat facing the US today is....

“The primary near-term security concern of the United States is the global economic crisis and its geopolitical implications. The crisis has been ongoing for over a year, and economists are divided over whether and when we could hit bottom. Some even fear that the recession could further deepen and reach the level of the Great Depression. Of course, all of us recall the dramatic political consequences wrought by the economic turmoil of the 1920s and 1930s in Europe, the instability, and high levels of violent extremism.” 
This propaganda effort is only a temporary measure and will not suffice over the long-term. As the economy continues to collapse, the banking elite risk being overthrown as a result of their own greed. So they will then turn to physical violence to suppress populations that can no longer be controlled through propaganda and economic coercion. The classic strategy of an endangered oligarchy is to divert discontent among the population into nationalistic militarism. It is time, once again, to bang the drums of war and whip the citizenry into a patriotic fervor. An increased external threat will lead to an increased internal crackdown, which creates the pretext and conditions for a police state. As we have already seen in the first phase of the crackdown on civil liberties since the “War on Terror” began, when rioting and outbursts of armed insurrection begin within the US, external threats, real or imagined, will again be presented to justify extreme measures to suppress American citizens, and to further repress internal dissent. Without an external enemy to rally the population against, the population will rally against the pre-existing internal powers.................  http://goo.gl/3ZIa5
