I don't think we should have gotten in Iraq -- not in the 90s, nor in the 2000s -- Saddam was a threat to the region, to Iran and Saudi arabia which is why Bush senior went after him
If Bush I had not interfered then Saddam would have used his robbings from Kuwait to fund a new war with Iran, possibly defeating it (with the USSR out of the picture)
He would also have held the Saudis to ransom
Oh and finally, the Islamic jihadis hated him, so they would have tried to get him and he would have used his characteristic mustard gas attacks on them
And there would still be 2 million Christians in Iraq living safely rather than 200,000 and dropping under danger from jihadis
Semi-secular Arab strongmen/dictators are sadly what is best for that region. They scare the Saudis (Which is fine by me), keep Iran in check (UN screwed the pooch in the '80s by holding Hussein back when Iraq gained the strategic advantage) and tend to keep "religious order" better than any Western "infiltrator" trying to "establish democracy" and nation build.
Muslims are a counter-hegemonic force that the West tries to desperately tame, but their "good intentions" make the situation far worse in the long run.
