re: So I’m Iran and want to start the war against the great Satan...

Im not sure of much one way or another on this situation yet, but here's a possible scenario: support for military action within the U.S., both citizens and Congress, appears to be severely lacking, and we'd have a tough time putting together a decent coalition. Knowing all this, Iran COULD be putting the U.S. in a tough predicament via small provocations that are extremely tough (for reasons stated above) to forcefully respond to, thus making U.S. look somewhat weak.
