That doesn't fly Dope. It's no secret that Putin doesn't keep any agreements. He will negotiate, sign an agreement, take the concession you made to get the agreement and pay no attention to keeping his agreement on his concession, and this was going on before 2014 and this dust up. Negotiations with Russia haven't worked so far. Remember, Russia agreed not to invade Ukraine and Ukraine would give up its nukes. That looks like a bad move now.

When Zelnskyy said he needs security guarantees, he really does.

This is a summary from the ISW:
