There is no good solution to any of this, both governments will be pushing to the end. Ukrainian government doesn't want to lose a large chunk of territory and Russian government doesn't want to let go now, since the loss will be seen as weakness and there is a huge interest in controlling the gas supplying line to Europe. Putin's reaction to Ukraine attempts to become part of NATO was going to be met with this type of violent reaction from Putin, who doesn't want to see NATO missile launchers even closer to the western border. AFAIC the American hands are all over this one, trying hard to create yet another distraction from its failing economy. Putin was easy to manipulate to start the war, but how do you end this war? A war with Russia can turn nuclear, so that is why there are no Americans or British or German or Canadian or other visible troops there yet.
Putin has a war now that everybody understands Russia is leading, but at the same time it is not an openly declared war, you can say it is an open secret war. Putin cannot win against the West but West doesn't want to fight a real shooting war with Russia either.
Stalemate. The only losers are the people who are forced into it on all sides, be it death due to bombing or bullets or sickness or be it economic sanctions (which by the way are not declared against 'others', economic sanctions are declared against your own. So economic sanctions imposed by Putin 'against West' are actually economic sanctions by Putin against Russians, it is just that the propaganda is strong, economic education and understanding is low and there is a tribal thing going on there as well).
USA provoked another conflict that may not end and definitely will not end well, good job. Putin is throwing fresh meat into the meat grinder, good job. Ukrainians are stuck between these two, like so many others before it, too bad.
AFAIC the only quick way out of this is for Putin to be assassinated or for Ukraine to give up and for the West to fuck off. All of these are unfortunate, but the alternatives do include a possibility of a nuclear war.
