Prediction: No NATO expansion to Ukraine (good), Putin gives back Donbas and Crimea, but keeps its naval base in Crimea a la Guantanamo Bay. Ukraine can form its own alliances with non-NATO eastern European countries for mutual security against the big bad bear. Putin saves face, Ukraine is saved, and everyone is content, if not happy. If Putin falls out a window later, nobody will cry.
Modification on Sevastapol. Russia can lease it for commercial, not military, shipping. Let’s get that Russian wheat shipped and keep the guns at home.
Putin cannot give back Donbas and Crimea and save face, but he may have no choice. If he does I don’t see how he survives, if he doesn’t I don’t see how he survives.
We will see but one option is Trump tells Putin withdraw or I will remove all restrictions on weapons abs weapons uses, additionally send pictures of all the equipment we have in storage, and say you ain’t seen nothing yet, and a few of his residences in 4k
There are no non-NATO eastern European countries that could offer even a sliver of security to Ukraine. Maybe you mean NATO countries forming alliances with Ukraine outside of NATO? Like Poland, Romania and the Baltic states? I think that's possible.
