You must be in denial. You can blast the "process" of lobbying and politicing all you want (which is surely ugly) but it's not the point. The point is that a nuclear Iran would be a lot more dangerous. For Israel its existential and fo the US (and all other Western states) a nuclear Islamic fundamentalist state which enables and supports terrorism is a disaster. If you are questioning whether Iran truly is trying to build nuclear bombs then maybe you have more information than I do. If you do please share. Before you bring up the question of Israel's alleged nuclear capability Israel is a democratic state with Western values and a history of having them for 40 years without incident. Iran is a different story with a fundamentalist regime that actively supports terrorists and openly encourages Israel's destruction. If you believe we should allow a regime like Iran to be in control of such destructive power then I would question either your intelligence or intentions.
