The problem that I see is that Bush will use his presidential authority to authorize air strikes in Iran, which will most likely include bombing their nuclear sites. This will be brought on just by the US saying that Iran is involved in troops being killed in Iraq. As long as that rhetoric keeps up, we will, more likely than not, commence air strikes in Iran if only for a couple of days. From there, things will prolly only go downhill. The idea will probably look a lot like the "shock and awe" plan that was set upon Iraq at the start of the war. I'm sure that the hopes we have, if we were to commence air strikes, would be that we create enough turmoil and havoc that we could also cause an uprising and regime change to take place. But weigh that against the negatives and any reasonable human being would probably come to the conclusion that that logic just don't work. However, I don't think we are fortunate enough to have reasonable people anywhere in this administration.
