We have attacked, Iraq, Afghanistan, Syria, Libya, Yemen among other countries. China? Russia? Maybe we need to clean up at home before condemning others.
Syria never happened and it should have. The Senate didn't approve going in. Assad committed genocide on his own people, with the help of Vladimir Putin. Allepo suffered the same fate that Putin is about to unleash on Kyiv.
Libya was a United Nations operation, not a US attack at all.
Afghanistan was sheer stupidity. And Iraq was no different than the Ukraine.
That doesn't mean we should stand by and let a pig like Putin just invade the Ukraine and murder anyone who gets in his way. He should have been stopped before this.
