This article points out the dangers involved in the coming war by the United States against Iraq. It first argues that the expressed reasons for the war do not comply with the Bush administration's objective of "regime change." Strategically, the administration has not shown the case that deterrence is no longer effective and they should risk invoking Iraq's use of weapons of mass destruction. The military action to change a regime and occupy the entire territory and population of Iraq is too bold to say that advanced US weapons guarantee a calm termination of the war. To expect that most Iraqis will defect is just an assumption. Geopolitically, the power vacuum in Iraq could lead to a collapse of regional stability. To keep domestic stability is also very difficult, given the ethnic and religious complexity of Iraq. Finally, the possibility of humanitarian catastrophes seems sufficient to be caution about the war.
