There is no equivalence between Ukraine and Iraq in the sense that what the west did to Iraq was much much worse, and Iraq posed no threat to us. That’s not to “defend” Russia, it’s to point out rank hypocrisy - yes, you're quite right.
The Iraq war (2003) was totally unnecessary, disastrous, and illegal. Saddam Hussein was no threat to the West. Hell, he wasn't even a threat to Kuwait in the early 2000s.
Putin's not stupid - he can probably see this hypocrisy, too.
How the hell can people like Biden and Harris condemn Putin's invasion of Ukraine whilst brushing Iraq under the carpet - it's just insane.
