I've read it. Some sources in there are interesting, but the material itself is completely disconnected from reality. In the sociopathic game of geopolitics, NATO expansion has certainly destabilized the balance of power and incentivized Russia to assert itself (and its claim on its former colonies). But you cannot compare countries forging military alliances, and a country invading another country... it's a completely different kind of escalation.

If anything, your article confirms that Putin is a colonialist bully just as much as NATO is in other parts of the world. It's just russian propaganda and does not account for mischief and imperialist ambitions on the part of Russia. If you want a more nuanced source, i'd recommend checking out Glenn Greewald's Twitter feed: it does a great job to denounce the hypocrisy of western powers, while at the same time acknowledging that invading a sovereign nation is always wrong, no matter what.
