Iraq too was supported by the West to attack Iran.
After several years, they abandoned it and iraq was left fighting Iran alone. It bankrupt Iraq.
So they asked the US if it's ok to invade kuwait to replenish it's finances and was given the green light.
But the president changed his mind later after the invasion.
And even much later the US invaded Iraq and executed Saddam.
A lot of similarity with current war in Ukraine. Except now, Europe has decided to take over from the US.
