I'm not sure how anyone sees similarities between these two scenarios: Scenario 1) US disseminates bad intelligence and invades a sovereign country. Iraq War.

I'm not sure how anyone sees similarities between these two scenarios: Scenario 1) US disseminates bad intelligence and invades a sovereign country. Iraq War. Scenario 2) US disseminates bad intelligence and arms / militarily supports a sovereign country which is being invaded. Ukraine. Nobody is remotely considering a scenario where the US is saying "Russia might invade Ukraine, so we're going to invade Russia." A defensive war is by definition the fault of the aggressor. Because they are literally on land that is yours.
