"We frequently opine on the question of what the U.S. should do about Iran and Syria. These countries raise serious national security problems — Syria because, among other concerns, chunks of it seem to be falling into the hands of terrorists whose ambitions probably include attacking American interests; Iran because it is determined to develop nuclear weapons with which to threaten, at a minimum, our allies.
Given these concerns, I believe the U.S. should provide substantial military assistance to the non-jihadist Syrian opposition and should impose new sanctions on Iran. Not surprisingly, the Obama administration does not agree.
But what, if anything, should the U.S. do about Venezuela and Ukraine? Both nations are led by anti-American, repressive thugs. In Venezuela, the thugs are virulently anti-American. In Ukraine, they are backed by Russia which has become solidly anti-American. But neither country poses a national security threat to the U.S."
