yes, its about getting nato in. but not every country in nato wants economic sanctions and rockets at the russian border. the main interest europe has in getting nato in to ukraine is to stop putin from destabilizing the country and gaining political momentum leading up to full on invasion. we know what happens if we let a man like putin occupy territories without consequence. he will take ukraine first, slowly, and then look to belarus, look to baltic states.
you say NATO is aggressive in positioning around russia, thats true as well. but that also has context. countries like russia and china and the USA are all waging covert wars in other countries, with propaganda, with soldiers with stripped insignia, with hackers and social media, with giving weapons to rebels etc. that is the real war going on now. all those rockets at the borders, in turkey etc, those are just flexing of some muscles, they will never be used
you are right that we do not bring freedom. that is american propaganda. NATO brings guns and mcdonalds. not freedom.
but imo its clear that the western social/economic model does give more freedom than the russian model under putin. if ukraine joins the EU and nato, then the EU will want to run the economy and nato will have military command. so they give up a lot of autonomy. but this was true for every country that joined the EU and/or NATO. and we benefited from it a lot. it is in the political and financial interest of most european countries to be a part of these organisations.
ukraine can choose to accept the west to make decisions for them or they can wait until putin spreads their buttcheeks and slides in.
