Well, foreign intervention kind of worked in Syria, Libya and Iraq after a few backstops, didn't it? All three countries reduced to rubble and virtually eliminated as threats to the US and Israel. Iran is next on the list, now that they're close to obtaing nukes. Let's not kid ourselves, they're not doing it for the Iranians, the're doing it for themselves. Regime change on their own terms, or if that isn't possible, yet another civil war.
