Rick Perry calls for a no-fly zone over Syria, and he floated that idea again in tonight’s debate. He either doesn’t understand — or he won’t admit — that a no-fly zone vs. Syria is the same as war against Syria.

Michael Knights, probably the expert on no-fly zones, told me during the Libya debate that a no-fly “is basically an act of war.” Knights argued that a no-fly zone was appropriate after a war, as in Iraq after the first Gulf War, or as the run-up to war.
