My opinion, and this is purely opinon, is that we have given him this much time because of two things: The UN and the general unwillingness of the majority of Americans to go to war, which is just a part of human nature. Saddam was not an immediate threat to our country for a long time in the past twelve years, and because the economy was riding high, we had no real need to worry about others. Twelve years later, this is not the case: our economy has lost a significant amount of its strength and the bigger issue of the EU in Europe between France/Germany and Britian made this war valid for our economic interests. By effectively spreading out the wealth that Iraq has, the US and Britain were really seeking to strengthen their own economies and Britain could use a stronger economy to its advantage in the power struggle in Europe.
