I completely agree with Mara here, Iran with a nuke is going to be the most devastating thing to happen in our modern times. Iran without a doubt will attack Israel directly or through a proxy terror group. The Shi'ite Iran government has and will continue on their path to returning Persian Empire, as well as their religious genocide of all Sunni Muslims and Jews and Christians. Anyone who truly believes that a nuclear armed Iran will not destroy any security/peace in the Middle East is a complete fool.
Israel will attack Iran, probably along with a NATO task force to keep Iran from possessing any nuclear capability. If these new economic sanctions fail (and they most likely will) we will have no choice but to attack Iran. The world’s economic trade security, the Middle East security and peace and the future of Israel all depends on Iran not possessing nuclear capability.
If we already know Iran would attempt a shutdown of the Strait of Hormuz with their chicken shit Navy, WTF do you think they will do if they have a nuclear capability? What do you think the world economics will look like with even a 30 to 90 day shut down/stall of oil trade from the ME, due to Iran simply rattling the nuclear saber? Much less a long term, drawn out military arms race and show down in the ME. Think Europe is in trouble now, think $5 a gallon of gas sucks, yeah let them get a nuke and see what happens.
