That impudent Iranian regime

"U.S. officials said they have seen no intelligence to indicate that Iran is actively plotting attacks on U.S. soil. But Director of National Intelligence James R. Clapper Jr. said the thwarted plot “shows that some Iranian officials — probably including Supreme Leader Ali Khamenei — have changed their calculus and are now more willing to conduct an attack in the United States in response to real or perceived U.S. actions that threaten the regime.”"  Let me get this straight: so the Iranian regime, while not plotting attacks on US currently, may consider responding to an American attack on its regime or territory?  How impudent.  Who do they think they are?  Don't they know it is against international law and decency to respond to US attacks on one's country?  It is just unbecoming.
