The world has sat idly and watched the Cuban Missle Crisis, China's bloody Cultural Revolution, Cambodia's Killing Fields, Rawanda, Vietnam, the Falkland Island War, 9/11 and the devasation of New Orleans. Frankly, in the event of a US civil war, most of the world would either shrug their shoulders or actively applaud.
No one is going to stick their military nose into US domestic issues to save anyone on either side until they know who is going to win.
yea. look around. people HATE us. if we started an internal war, people would love it and cheer for as many deaths as possible -.-
