Assume that Iran herded tens of thousands of Iranian protesters into a coastal enclave and was systematically starving them to death. Assume that, recently, it had exterminated hundreds of Iranian children (with white phosphorous, for example) of those who had voted for Mousavi (and who consider the current government of Iran "illegitimate"). Assume that a U.S. ex-Congresswoman was arrested by the Iranian authorities in international waters for her attempts to bring humanitarian supplies, and was then imprisoned by the government of Iran. Would the United States ignore this or would it consider it an act of war?
