This has nothing to do with anything in recent history. Iran has been at war with the United States since 1976 because Jimmy Carter was a coward. Carter could have saved the US forty years of terrorism if only he had some courage. Iran funds terrorism, even Democrats admit it. So the fact anyone has the nerve this attack was "unprovoked" has no concept of history. Take a good look, unlike Iraq, the US was welcomed to Iran as liberators. People must understand we're not "nation building" we're helping to restore a nation back to the way it was almost 50 years ago.
