Both, since one is a part of the other. The way I get it, the major asymmetry between the two cases is that the US invasion of Iraq was the initial phase of the Iraq war (which had already ended), whereas the Russian invasion of Ukraine is the terminal (and current) phase of the Russo-Ukrainian war (which hasn't ended yet). So if you're talking about these things today, it makes perfect sense to talk about the invasion in progress as it's the current event. If you bring up the Russo-Ukrainian war in a conversation, it's unclear about what part of the events since 2014 you're talking about, since presumably if you were talking about the current events, you'd be more specific. If you talk about the Iraq War, there can be no confusion with current events since it ended a decade ago.
