It makes no sense to "invade" Iran.

We may conduct a pinpoint strike against nuclear facilities or support an Israeli strike, but a full-scale invasion is pointless.

This is because Iran has a large-scale reform movement and wants closer ties to the U.S.

Also, the Shiites in Iraq will serve as an example to Iranian Shiites. Hopefully the democracy in Iraq will inspire others in Iran and elsewhere.

I think Iran will probably end up as a nuclear power. As long as they do not support terrorism, I don't care. Everyone is going to have the bomb sooner or later. Maybe this is for the better. Then everybody has permanent country insurance. good old mutually assured destruction prevents things like pre-emptive invasions. If Iraq had a nuke, we never would have invaded.
