I believe it should be crushed. Thanks.
You seem to believe that the US should attack any country we don't like. Megalomania, kinda like Hillary.
Iran, Syria and North Korea all have long histories involving the murder of Americans and others, both inside their borders and abroad.
Diplomacy may indeed work, if it's backed by force, and a United States finally willing to see such moral stuggle through rather than abandon it once the political elite becomes intimidated out of it by the international left. Unfortunately, that latter aspect marked most of the second half of 20th century US history.
