Why would they 'give up on Ukraine'? They consider it theirs, or at least in their zone of interest politically, geographically, culturally, historically, strategically.
They would give up on Ukraine if the alternative would be the disintegration of Russia and complete collapse of the regime.
If the West applied economic sanctions in a meaningful way, coupled with more help for Ukraine including capabilities to strike deep inside Russia (Especially against economic targets), and also arm some rebelions in Russian republics with large demographic minorities like Dagestan or Ingushetia, the Russian regime would be unable to sustain the war on multiple fronts while having a collapsing economy.
Some retarded politicians in the West would say this is a dangerous scenario because Russia would go nuclear, so they try to avoid it, while the reality is that this is an ideal scenario where the Russian regime would come to the negotiating table and withdraw from Ukraine in order to avoid its collapse.
Unfortunately the West is run by politicians even more cowardly than Putin, which is something really shameful.
Even a conventional hot war with Russia is something Putin & Co are well aware the west wants no part of (even though, yes, the west would win that showdown, duh). They're not going to 'give up on' Ukraine for the simple reason that they've called our bluff, they know we don't have the stomach or will for a fight like that anymore.
It is all about the incompetence and cowardly nature of Western leaders, it has nothing to do with having or not having the will to fight. Russia could have easily been defeated even without NATO engaging them directly, simply by applying real economic pressure, giving more lethal help to Ukraine and funding rebellions inside Russia.
Ukrainians and Russian minorities who hate the regime would have done the fighting for the West if given enough support. And the Russian economy would have collapsed if it were put under real sanctions, not the jokes currently imposed on them.
Certainly not over a little place like Ukraine that, let's be honest, about 3 years ago Average Joe/Jane American or Brit or whatever basically just thought of as "Russia-lite" anyway. All of those former-Soviet states blend together for the normies, and every western leader's damn well cognisant of the fact their population has no appetite whatsoever for sending their sons over there to teach Big Meanie Russia a lesson on good international etiquette. Or be responsible with providing stuff to rain hellfire down on Russian cities with.
This is because Western leaders are no better than the regular normies who can’t point their own country on a map. They are unable to form a coherent strategy to defeat Russia, not because they lack the means, but because they lack the will and the intellect.
It's about all you can do, and it's obviously not going to be enough. Sucks, but better than the alternative, that's the western calculation. "If Putin's dumb enough to go into Poland then obviously it's fucking on, but Ukraine's a pretty unique situation not rising to that bar. Best of luck, homies, here's some boom-booms we can spare, just don't do anything stupid with them."
No, it is not “about all you can do”. It is what the treacherous Western leaders are willing to do for a country they encouraged to decouple from Russia and take the risks associated with that.
The insanity is so high that they care more about energy prices than they do about a war in the heart of Europe. They even continue to talk about nonsensical issues like climate change when there is a big hot war in the middle of Europe… How much more delusional these people can be?
