Quotation needed. And no, Ukraine does not count. They had a vote and voted to be part of Russia; that's a far cry from rolling in the tanks and taking it by force.
They did send in their military, that's who the "Little Green Men" were. Even Putin has publicly admitted this. The "vote" was held under occupation, not internationally recognized, boycotted by significant segments of the population, and even Russia at one point accidentally released the "real" numbers from the vote which didn't match the official ones.
Do recall that Russia is a country where Chechnya "voted for" United Russia (Putin's Party) 99% in 2001. Some parts of Grozny voted for "The Butcher of Grozny" by well over 100%. You seriously think that's legit?
Amazing how many apologists for Russia there are here. False equivalencies are clearly alive and well.
