Certainly not every intervention was a great idea, no, but that doesn't mean the right thing to do is never intervene. I'd argue the right thing to do is learn from that and not do that again.
So what interventions after WW2 do you support?

The intervention in the Korean war?
The intervention in the Vietnam war?
Intervening in the Laotian Civil War?
The Permesta Rebellion?
Lebanon crisis? Bay of Pigs?
Invading Panama? Invading Grenada?
