Nations faced with illegal physical assault by the U.S.---here Iran is an example as the U.S. has even threatened to use nuclear weapons against it---could announce they will not fire back or oppose invasion. If this seems like a lot to ask, consider the alternative: the futility of stopping U.S. "bunker busters and "daisy cutters or missiles fired from offshore warships (as columnist George Will has recommended in Afghanistan).
It should be obvious the best way to fight fire is not with fire but with water. And the best way to oppose violence is not with more violence but with non-violence. While each situation is different, a nation facing illegal assault might consider the following steps:
Declare before the United Nations and to the media that it will not use force against any invader. In such cases, an invader that comes in shooting will betray its criminal intent before the world.
Request that the invader submit its grievance to international arbitration.
