Just like any other country, there are factions in the Iranian government that are unhappy about the rapprochement between US and Iran. They probably profited handsomely from the sanctions (just like Saddam and his sons did in Iraq, years ago). They're unhappy. And they're making these ridiculous provocative gestures to provoke the US.<p>The last thing that US needs to do is get provoked. Ignoring the idiots is the right course of action. But will the US do that? I doubt it. Because we have our own set of idiots too, who love to play cowboys.
