US and Israel can take out Iran I doubt the Saudi's will mind in fact they will support them. So much for Muslims being brothers.
I am not so sure. Sadam Hussein and Iraq were a bunch of choir boys compared to Mahmoud Ahmadinejad and the Ayatollahs in Iran. Hussein never talked about wanting to exterminate Israel / wipe it off the map, where as these guys are proper lunatics, and I don't think its all talk.
If the US went to war with Iran I think it would be their new Vietnam. I am not sure they could win without turning the place into glass
