Georgia 2008, Ukraine 2014, no, it's not "individual localized", it follows the pattern of Putin attempting to resurrect a totalitarian dictatorship, collapse of which he not-so-subtly called the greatest geopolitical catastrophe of the 20th century.
How does it not "make sense at all" for Ukraine to acquire defensive capabilities after the aforementioned aggressions? Surely it makes at least some sense if you really want to step back and take a look at the whole picture and not just Putin's "interests".
No, it's still actually quite clear, no need to muddy the waters here. If Alice robs Bob's house and Carol's house and Carol buys a baseball bat and Alice comes back to rob Carol 8 years later, no sane person would think that this is complicated or nuanced.
After Saudis double tap a Yemen funeral with a 500 pound laser-guided bombs manufactured by the United States resulting in 155 killed, US sells $110 billion in weapons in 2017 and $350 billion over 10 years to Saudi Arabia while Saudis are still involved in the Yemeni war causing (8,672 civilians killed and 9,741 injured by coalition's airstrikes) and no one bats an eye, the war is still ongoing. Russia starts a conflict in Ukraine with 406 civilians killed and everyone looses it, Russian funds are stolen, every mass media is covering the war almost 24/7, major cities light up their buildings in the colors of the Ukrainian flag, online warriors are activated and put Ukrainian flags in the profile, and people want to start WW3 by asking NATO to start shooting down Russian planes ("no fly zone"). Clearly all due to the loss of human life and because Saudis are not a dictatorship
Our propaganda is better than their propaganda.
