Russia (aka the Soviet Union) has done plenty of interventions since the start of the Cold War.
Thinking that Ukraine compares to Iraq is simply incorrect. I didn't support the Iraq War, but as you can see today -- the US's end state there was not control over the country, gov, or people. That's verifyable.
Russia has verifiably ANNEXED land and people, and its public goal is to destroy the democratically elected gov of Ukraine. Even in that regard, Saddam was a dictator.
It's actually pathetic to compare Russia in Ukraine to Iraq. I don't think even 1 Ukranian would agree with you.
