But big obstacles remain. Senior U.S. officials are chafing at Russia's continued flagrant violations of major arms agreements, including illegal development, production and stockpiling of undeclared next-generation biological and chemical weapons. Moscow still ignores U.S. pressure to stop proliferating nuclear and ballistic-missile technology to Iran and other rogue regimes
Just says enough. Just think of it: Iran getting missiles AND nukes. Israel and the US will be pressured to react. And that could spark a large scale war (Saddam is crazy enough to do anything).
