This plan doesn't fit Trump's character.
I'll try to suggest a plan in line with Trump's character.
In a complex business negotiation, you need to be at least on equal footing, or prevail over the other side. And have trump cards up each sleeve.
The non-Trump signed Lend-Lease, for example, can be initiated in supplies, and on the front create localized but radical superiority in some areas. The supplies are serious. Three hundred airplanes, thousands of tanks and bmp, cruise missiles in abundance. The capture of the Kursk Republic. Strikes deep into Russian territory. No-fly zone over the fronts. At the same time on economic fronts, some actions aimed at strangling the Russian Federation. And shut down the Baltic immediately.
Half a year. And then - negotiations. We give you yours, you give us ours, and Ukraine completely goes to the West. At the same time, pressure on the friends of Russia, so that they all do push-ups while Puilo eats dates.
The negotiating position is carrot and stick. Puilo doesn't want to pay reparations - well, don't pay (aiming for "later"). And if you don't want to negotiate like this, your tankers will be drowned by Ukrainian submarines on all oceans, independent republics from the former Russian Federation will be recognized, as well as their governments in exile. And a complete embargo on all movement across the borders of the Russian Federation.
