You are describing a fantasy fiction, but reality is not that simple. Putin’s actions were very rational by Western standards of reasoning (NB not moral standards). His invasion had a point, but was based on bad intelligence and some logical flaws, just like American invasion to Iraq two decades before. He is no more crazy than Chinese or Iranian leaders and probably more sane than current American administration. He is absolutely ordinary man, a grandpa who accidentally came to power, is afraid of retirement and whose views were influenced by external factors. He is not a philosopher, he had not written lots of books on his ideology etc. He is not on a mission, even if he may dream about it. He just steers the wheel and seizes the opportunities. If you look further in the past, the whole Ukrainian conflict may have started from a single naval base in Sevastopol, loosing which would be a major blow in the chess game. And then one escalation followed another, leading into current quagmire. And he was just carried in the stream. He has no exit strategy but to wait for something to happen. NATO just need to hold firm and have enough presence on borders to make blitzkrieg impossible.
There was no threat of losing Sevalstopol, which was leased until 2049 in non-aligned and then substantially pro-Russian Ukraine. You build your whole chain of reasoning on a faulty premise.
>There was no threat of losing Sevalstopol, which was leased until 2049 in non-aligned and then substantially pro-Russian Ukraine.
This is not correct. Kharkov agreements in 2010 extended the lease until 2042 in exchange for gas price discounts, but they would start working only in 2017 and Ukraina could cancel them (and may have cancelled them if anti-Russian opposition would be back in power - the threat of losing the base was real). After annexation of Crimea Russia itself cancelled the agreements and they effectively were never in place.

That was not the premise for the whole chain of reasoning. Premises do not start with "may". :)
