Please discuss one of the following questions in the context of American Exceptionalism:

• What's worse for the US—being over-involved in dealing with international ills or allowing evil to run free? The US has supported some pretty shady rulers over the last 50 plus years of foreign policy, all in the name of fighting the spread of Communism and, more recently, combating terrorism. In the past, what would have been worse—letting Communism spread freely or supporting questionable leaders? 
• Does the same philosophy apply to preventing terrorism from spreading? Or is there some sort of middle ground in preventing these dangerous ideologies?
