Russia has massed and withdrawn multiple times since November ... essentially trolling NATO
Any possible link, that is not including the so called withdrawal of troops last week.
Demanding what was promised is not aggression, if the USSR did not let Ukraine go there would be no Ukraine, if the guarantees made to the USSR were how they were convinced to let Ukraine (and others) go, then the demand is only natural and nowhere near aggression ... the ones breaking that guarantee are far more aggressive
Who promised who? Would like to read up on that.
The USSR does not exist anymore and Russia has no legitimate claim to Ukraine. The USSR declared Ukraine independent in 1991.
NATO was explicitly created to counter the Soviet Union, it has literally no other reason to exist ... you wouldn't be concerned by a multinational military alliance focused specifically on you?
I think the existence is clearly justified. Georgia 2008, Crimea 2014.
Incorrect, Russia had agreements in place with Ukraine to keep a naval base there forever i.e. they certainly didn't invade as their troops had a legal right to be there
Secondly: there was an actual referendum, the west can say what it wants, you can find enough independent documentaries of Crimean people on the ground confirming they all did in fact vote to become part of Russia
Yes, so only the base was considered Russian territory. You clearly forgot to mention the Russian troops and vehicles across the Crimea, and troops giving the Ukrainian soldiers an ultimate that they are to leave the bases or force will be used. The Ukrainian government was threatened that if any defence or resistance was set up by the Ukrainian military, Russia will continue to invade the rest of the country.
Yes there was a referendum, and it might be that the people of Crimea wanted this, but there is still a big doubt placed over the legitimacy of the referendum. Just look at what happened to the Crimean parliament in late February 2014 when it was taken over by armed men (most likely Russian SF), and immediately the current PM was voted out and replaced by a Russian Unity Party member, a party which only had 4% of the vote in the previous election)
