Don't bother, most of the people with an interest in discussing Russia have not one iota of understanding of the difference between 'invading' a country and 'annexing' it, or they choose to willingly conflate the two since it works against American's interest in this discussion:

Russia annexed Crimea.

America invaded Iraq.

Well yes, America's "invasion" was a muddle of confused goals & retaliation while Russias "annexation" was conquest. You're quite right that they're different. One does massive incompetent damage while not intending to stay, the other does its damage deliberately with an eye towards the long term health of their newly conquered territory. Russia's imperial ambitions on their western borders aren't exactly new.

Your attempt to cast Russias annexation of territory it has had claims on for hundreds of years as a misdeed isn't really effective. There were actual Russian civilians being protected by Russian forces during that process. There was a fully armed nuclear base that was under threat of falling into the wrong hands during the Ukraine uprising (which, incidentally, the rest of the world knows full well was funded by the CIA).

Iraq lost 5% of its population during the American invasion.

How many Americans were in Iraq, who were under direct threat of violence from a fascist group involved in a coup d'etat?

Russia hasn't reached America's level of evil, destructive, criminal warfare, that is for sure. The claim that America was surgical and careful in its invasion(s) is specious at best, but really just downright evil. Literally millions of people are still suffering from the effects of America's callous invasion.

4 million innocent people have lost their lives under America's war machine. How many Ukraine soldiers did Russia take during the annexation?

Not even comparable levels of magnitude, no matter how finely tuned your moral relativism chops are ..

Every single statement you made is wrong.

All of the Ukraine color revolutions were clearly US / CIA / foreign intelligence agency backed (https://www.theguardian.com/world/2004/nov/26/ukraine.usa). Both the EU, Germany and the US had their favourite political operatives in the fight. Various NGOs including German ones paid protestors daily stipends to continue protesting on Maidan, provided them with food and other assistance.

There is no question that the irregular forces in Ukraine received military equipment from Germany, US and other sources. There is videos documenting that. Part of the anti-russian forces were literal neo-nazis, complete with insignia used during world war 2. The Vice magazine war reporting (Russian Roulette in Ukraine) documents both of these statements.

Americans very shrewdly avoid the fact that their state was supporting literal neo-Nazi's in Ukraine. It seems they are caught in a caldron of misinformation and simply do not care for the truth, as long as it distracts the world from the other things America is doing, as a nation, around the world.

No, it really isn't.
