Ukraine should do what they want and what's best for them. The rest of us should fully support Ukraine. Their lives are worth more than our guns. For as long as their government can field troops we make sure they are equipped and trained. It's supremely arrogant of us to suggest how these people should or shouldn't conduct any peace agreement with Russia outside their request for our thoughts. They will run out of soldiers long before we run out of guns.
But...
The rest of us should continue to isolate Russia. Not a single sanction is lifted, and we continue to isolate them harshly, even after they claim peace with Ukraine. More sanctions. More restrictions. No invitations to world events. More seizure of Russian assets. Entire sections/ministries of our governments created to deal with Russia and their ilk. More security against Russian actions and their corrupting money in other countries. Russia is a cancer that works against us all, we need to treat it as such. Even when Putin is dead in his bunker from old age we show no mercy for the kleptocracy Russia is. No easement without Russia peacefully returning all occupied land to Georgia (in Abkhazia and South Ossetia), Moldova (in Transnistria), and Ukraine (in Crimea, Donetsk, Luhansk, Kherson, and Zaporizhzhia) AND full, transparent, overseen democratic election process, and then very very slowly. We relentlessly isolate them more and more.
Countries are like organic cells. We need to isolate and starve the bad cells or else they infect those around them.
