I think the US went without UN approval because we\'ve been waiting for Iraq to disarm for over 12 years now. Frankly, after that long, the US government is growing a bit impatient. Theres only so far you could push a government before they react. We\'ve had our embasys bombed, buildings attacked, troops attacked, bases bombed, the Cole, killing innocent civilians as in 9/11, kidnappings like the US embassy in Iran and Daniel Pearl and theres only so much the US government bent over backwards and ignored this. Now the government has had enough and is taking action for all these attacks and kidnappings against America.
