Russia’s foreign policy since WW2 has been driven by the fact that they were utterly terrified of external existential threats. They suffered so greatly in WW2 and came so close to destruction that they were determined that an invasion would never be fought off in Russian soil again. So they gained influence with satellite states to create buffers between the western powers and Russia itself, and formed its military doctrine around all-out offensive with the plan of having a potential war being fought in the west, rather than the east, regardless of who started it or why.
When the Soviet Union collapsed, we had a chance at a relatively peaceful situation from a beaten down Russia. All we had to do was reassure them that they needed fear an existential threat from us, that we weren’t going to exploit their weakness and use it to strengthen ourselves in their backyard.
And what did we do? We poked the bear incessantly. We recruited former Soviet statellite states into NATO. We tried to exert influence - cultural, political, and with subterfuge - to influence the governments of countries that bordered Russia.
So when we supported a popular uprising in the Ukraine, Russia’s historically most integrated ally and the country that borders its most vulnerable areas - essentially the most vital country you could fuck with if you wanted to scare Russia - and we helped to sow descent and specifically ran programs geared at influencing the Ukranian government to be more pro-west, it was an extremely aggressive action.
Most of the Russian leadership wanted to simply rebuild their economy and solidify their own wealth and power, but there were always old Soviet hard-liners who were hawkish on foreign policy and tried to play up the western threat. By taking reckless actions like trying to move NATO further east and destabilize Ukraine, it gave credence and fuel to those hawks.
We couldn’t simply be satisfied that the cold war was over and relations with Russia were peaceful. We had to go stirring up shit and try to re-ignite the cold war. Why? My first guess is that monied interests benefited greatly from the cold war and peace is bad for business. It turned out creating a new Russian threat wasn’t even necessary - they got their way of keeping up the military budget in the form of an eternal war on terrorism and kicking over shitty countries. But I suppose when the American people got fed up with spending treasure and lives across the world on places that weren’t a real threat, maybe it was time to resurrect something that actually was a real threat to keep the machine going.
The current Russian aggression is almost entirely a reaction to these factors. The OP proposes we go stepping this process up by trying to stir up shit in even more satellite states, justifying further Russian aggression because they’re responding to a real, legitimate threat from the outside, and not just bullshit war mongering.
We could’ve had an era of peace and prosperity with Russia, with trade and good will, but instead people who still had hardon for the cold war and a financial incentive for the US to always perceive some sort of threat in the world are striving to re-create it.
