Your point hasn’t been proven. OPs point was that Putin promises can’t be trusted. And without US putting force behind that promise, Ukraine is wise to be worried about such a deal.
Just because one alternative realized doesn’t mean there weren’t other options, better or worse.
Edit: plus, a peace deal is far from done, regardless which side you root for.
Doesn’t matter, your life will be ruined either way by everyone around you that wants a piece of the pie.
Life pro tip: don’t win the jack pot. And if you do, keep it as much a secret as possible.
