Lantos Introduces Iran Sanctions Legislation

I don't really have any idea why we are imposing sanctions on other countries that by into Irans nuclear power. I understand that they may be led by somebody crazy, but this will only affect our relationship (which is alreay in shambles) with our foreign allies. Also if we were so worried about what they are capable of, then wouldn't you try not to irritate the madman. All they are doing now is egging these extremest into a political area we simply aren't ready for.
