Eight questions on Iran

If the U.S. attacks Iran,

1. Will Iraqi Shiites start fighting the U.S. as strongly as the Sunnis?
2. Will Iran invade Iraq?
3. How will Pakistan respond?
4. How will China respond?
5. How will Russia respond?
6. Will we get our butts kicked like the Israelis in Lebanon?
7. Will the military refuse to carry out such a boneheaded scheme?
8. After stating publicly and specifically that they have not authorized an attack on Iran, will the Congress have the balls to impeach?

The utter insanity of attacking Iran leaves me (almost) speechless.
