I've been thinking about this a while and I saw this last night. I think was are totally justified and within the Constitution to ban extremist Islam in the US. We should require all Muslims to register, and if we find out they are extremists, deport them or jail them on the basis of treason.
The situation in Iran makes it all the more important that we have a huge presence in Iraq. We should also have a defensible border with Iran- two strips of barbed wire 1/4 mile apart and kill everything inside of it. The so-called civil war in Iraq would quickly boil down, without the Iranian influence to fuel it.
We also need to let Israel do what needs to be done with the current Hezbolah issue, and provide support with an embargo on Iran during this whole process. Just like we are doing with Castro and Cuba. Maybe if we isolate the little bastard he will be overthrown from within. The only other option I see, due to the current US political situation, is to wait until Iran nukes Israel before we watch them completely destroy the current regime. Hopefully that will happen before Iran attacks New York.
