Skilled negotiators recognize that sometimes an agreement satisfactory to both sides cannot be reached. In multi-lateral negotiations, its even harder to reach agreement. In this case, all El Rey Dotardo II cares about is 'making a deal'. Whether that 'deal' satisfies all parties is secondary. In the case of the Ukraine war, some on the right now treat it as a tar baby, to which we're stuck. The key to getting Russia to make a real agreement that will satisfy all parties is to continue to arm and support Ukraine, and even so, the war will grind on for some time. Russia will eventually quit this stalemate (see also, Afghanistan) and between now and then will be preoccupied with the war to the point where it cannot create much mischief elsewhere in the world.

The sticking points will be (1) Ukraine joining NATO (um, hello--they are already a de facto member--note the weaponry) and (2) Russia giving back Crimea and the children kidnapped from Ukraine. It may be that Z will have to give up on #1, in exchange for #2, and building a much bigger war machine for the future...
