I am sure if I am wrong I will be corrected on the
two counts below:

Sadaam through the UN sanctions was allowed
to buy food and medicine for his people with Iraqi oil.
But he inriched himself while his
people starved.

Back in the Gulf War, I also believe Pres. Bush did
want to finish the job, but because of
UN pressure we left. (this is why the kurds and the Sheit
muslims lost trust in us during the uprising 12 years back)
Thus the UN sanctions and also the UN resolutions
that Sadaam was not to have weapons of mass destruction
etc. was put in place.
If the UN had than made sure that Sadaam followed
the resolutions, then the US/Britian would not be
in Iraq today?
