Ok, I’ll bite

1. How has Russia invaded Transnistria? Transnistria was a breakaway region during the collapse of the Soviet union, similar to Gagauzia
2. No one disputes that Chechnya is Russian territory. Russia cannot invade its own territory.
3. Georgian military intended to genocide ethnic minorities. Russia supported the autonomy of said minorities.
4. Crimea was given to Ukraine by Kruschev very recently. It is almost entirely ethnically Russian, and those ethnic Russians voted overwhelmingly to secede during a coup/constitutional crisis as the alternative was staying in a country where there culture and language are banned, or worse become the target of hate crimes from neo-nazi battalions as many cases are well-documented
