Re: Should Iran be attacked?
Sure.
"Diplomacy" will fail, Russia and China will try to protect their economic interests, Iran will continue their hostile belligerence, and the US will step up and use the least lethal weapon available in an effort to minimize world opinion against the US while delaying the Iranian program.
The way Iran is acting now, they are almost asking to be attacked. There is some plan in their mind to ignite a conflict. The US will not back down from that challenge. Next stop North Korea.
