I don't.
I'm wondering why the Israeli war game included it.
On Jan. 9, 1991, on the eve of the Gulf War, then Secretary of State James Baker issued a private warning to Iraq. At a meeting in Geneva, Baker told Iraqi Foreign Minister Tariq Aziz that if Iraq used weapons of mass destruction against U.S. forces, "The American people will demand retribution, and we have the means to exact it." That carefully worded, nonspecific threat was meant to raise the possibility that the United States would use nuclear weapons against Iraq if it used chemical weapons against American troops. Baker has since told acquaintances that he doubts whether then President George Bush would have actually used the nuclear option, but that the threat may have been a deterrent.
Probably because they see how Saddam upped the ante in terms of what he is willing to do on the US mainland with the destruction of the WTC and the subsequent anthrax threats. The next phase of our ten-year war with Saddam Hussein isn't going to be a nice, tidy confrontation between B-52s and massed troops. It will involve terrorist proxies using weapons of mass destruction against American and European cities, as Dick Cheney recently explained to Tony Blair.
