Did they teach you that in school, Samantha?- 
"U.S interventionist/imperialistic warfare."
You mean like WW1 and WW2? Korean War? All of these we won, and yet I see none of those countries taken over by the U.S. to support "imperialism".
As far a "interventionist" sometimes all it takes for evil to prevail is for good people to just sit back and do nothing.  Should we have just sat back and watched the people of Europe be slaughtered by Hitler? Or, should we have done nothing to Imperial Japan after being attacked, and just let the slaughter continue by the Japanese all over Asia, and the South Pacific?
You can save all your America hating name and calling.
