Why did the US get involved?
The implimentation of the 1991 Gulf War by the US led coalition was intended to serve a number of purposes. For starters, it was useful to demonstrate to the world that any threat to American interests would not be tolerated, particularly where these interests required the unimpeded supply of fuel to the world's most energy proliferative nation. It signaled the new global power structure, "New World Order" in which a post-Cold War US could operate without the bothersome constraint of another global superpower. It was therefore necessary that Iraq be mercilessly crushed.
The weaker opponet "must not merely be defeated but pulverised if the central lesson of World Order is to be learned: we are the masters and you shine our shoes."(1) -Prof. Noam Chomsky
The primary purpose of the US-initiated war on Iraq was not the expulsion of Saddam Hussein from Kuwait. It is obvious that the US has no objection to agressions by sovereign states against others. For example, the US didn't raise a finger in military opposition to the Israeli invasions of Lebanon and other Arab lands; to the Indonesian invasion of East Timor; or to the various South African invasions of Namibia, Angola and Mozambique and of course the US itself has invaded many sovereign states (notably Grenada and Panama in recent years).
The war on Iraq was designed to protect US interests over oil, to educate the world about post-Soviet political realities, to test new anti-personnel and other weapons, to justify the absurdly high levels of investment in US military power, and to leave Israel as the sole regional superpower, which has, in comparison, committed an order-of-magnitude worse version of Iraq's sins: invade another country, manufacture weapons of mass destruction and violate more security council resolutions than any nation on earth.
