Are you talking about Saddam's invasion of Kuwait?
What , you mean when Saddam thought it would be simpler to get rid of Kuwait rather than paying them back the money they had given him to help finance the worlds proxy war with the Ayatollah ?

The Kurdish problem hasn't been caused by the U.S. it has been caused by their neighbors. Make 'em independent and let their neighbors suffer the consequences.
Ahhh , that would explain why Turkey was just a little bit wary about supporting this madness then .
Iran would seem to be the only major winner out of this .
That would also probably explain why it had its agents feeding the American governmnet lies by the bucketfull (which they were only to happy to lap up) .
Iranian based Shia groups dominate the new Iraqi "parliament" , Iranian backed Kurds, very well armed I might add , have the edge in the Kurdish assembly , Iranian based clerics are going to be drawing up the new laws for Iraq (with sharia law superceding any other law) The US has become isolated internationally and divided internally over a very unpopular and expensive war and had its politicians credibility sent to an all time low .
It has tied down the major power that could threaten it in an appalling mess that it cannot get out of and has also had that power eliminate its two regional enemies . Add to that the fact that Iranian backed groups are on the ascendancy politically in Palestine and the Leb (Egypt as well if they ever had free elections and released the opposition from jail) and they now have a free hand to develop their own nuclear program and no one can really stop them .
So whether Iraq is split or stays united there does seem to be only one winner out of all of this ...the theocracy of Iran .

Oh and all that oil they are sitting on has had its price go through the roof .
