Russia did not invade the Ukraine. If you refer to Crimea, they were asked to help because of the threat from the illegal coup regime which are a bunch of Russian haters.

Putin said it did not, he said soldiers on vacation leave went there on their own, and the equipment was bought at the local military shops.

Why did Nuland & Co invade my hometown?

Who knows

You ask it in a million refugees who arrived in Russia - why they are running the country which they were attacked? In my town came to 1,000 refugees from Ukraine. You do not find it strange that they were going to the aggressor?
