I wish they didn't have to wait for things like this. It sucks that Ukraine is at the whims of other countries while it's trying to fight to maintain its sovereignty.
It makes me so depressed thinking about how many thousands of Ukrainian lives could’ve been saved by just giving Ukraine full and enthusiastic support immediately instead of dragging it out this long.
This was done on purpose so the crisis didn't escalate. There's no world police to prevent Russia from nuking everyone. It's better for outside actors to focus on de-escalation anyway.
Also, Putin is not doing this because of Ukraine. I mean that's part of it, but he is doing it for domestic appeal. He wants to appear tough to Russian citizens. Two situations allow that: beating Ukraine easily, and losing to NATO forces. He knows NATO will not risk invading Russia, so he's in no real danger from the second one.
NATO is intentionally not intervening because it makes Putin look weak domestically. Russia has created their own problem and the war will not end until the people of Russia demand it.
That's Putin's doing. His bluff was strong and he had a big pile of material, so the West is using a Russia technique known as the salami slice method, by slowly escalating and gauging the reaction from Putin. It means no world war 3 scenario, no allies that have to come to his defense and also not letting Putin taking whatever he wants with just bluff and threatening speeches. It is costly in lives and material though.
The US has too many bases to defend simultaneously to engage with Russia directly. It would be the 18th Anglo-French Wars all over again but with the possibility of a spicy nuclear conclusion at any given moment.
Keeping the conflict contained to the Ukrainian theater means western states get to "bleed" Russia in a protracted conflict without drawing the rest of their assets into a firefight. But we're already seeing the US/Russia conflict leak into the central African states, the Korean border, and recently the coast of Florida.
Americans don't actually want this to become a full blown World War. That drives up our defensive costs significantly and skews the "Stupid Russians Lose Again" headlines with a bunch of "Brave NATO Soldiers Fucked By Insidious Russian Treachery" articles.
“Destroyed"? Don't you mean "killed" columns of Russian soldiers? Even if they are in the wrong, these are still lives that are lost, not some equipment.
In the military it's common to talk about groups of soldiers the same way you talk about equipment. Because the crucial information isn't their humanity, it's their utility to the war effort. "Destroyed" is usually used to mean a unit is so broken it must be combined with other units and different militaries have different definitions of exactly how many casualties that takes.
