HOUSE OVERSIGHT 029808 the lead-up to Iraq's invasion in 1990. When faced with a build-up of Iraqi forces along its border, Kuwait decided not to mobilize its military out of fear that the move would provoke Saddam Hussein. The incentives for Gulf states to make similar strategic calculations in the future will be greater when Iran has an inventory of nuclear weapons to match its growing ballistic missile capabilities. The Gulf states, moreover, will likely reason that the U.S. capability to threaten or use force against a nuclear Iran will be significantly diminished. Even without nuclear weapons, Gulf states have seen, in their view, a long history of American reluctance to threaten or use force against Iran. For example, the United States took no direct military action against Iran after it aided and abetted Hezbollah bombings against Americans in Lebanon in the 1980s, after Iran supported the bombing of Khobar Towers in Saudi Arabia in 1996, or even after Iran supported the deadly campaign of improvised explosive devices (IEDs) against U.S. troops in Iraq. Gulf states will no doubt judge that if the United States was unable and unwilling to attack Tehran under these circumstances, then it is certainly not going to attack Iran in the future, when it will be able to retaliate with nuclear weapons.
