There isn’t. There’s also no point in continuing a strategy that clearly favors Russia (they’re the ones steadily gaining ground every month).

The better strategy (which Trump almost certainly won’t entertain) is to negotiate a peace now and use that time to build a robust defense-in-depth at the current border.

It will be ugly because it will turn miles of border into a dangerous DMZ. But Russia already demonstrated that it works. Dig a crap ton of trenches. Build out bunkers and anti-tank traps. Ignore Geneva a bit and mine the crap out of the area. Lots of surveillance. Probably some experimental infrastructure to make it easier to deploy drones.

That would also need to be coupled with commitments to build out munitions plants in Western Ukraine; primarily artillery shells and drones.

This will work because it dramatically raises the cost of each meter of ground gained by opposing forces. Ukraine can get defensive infrastructure that they can cheaply operate, without significant external assistance.

The downside is that Ukraine would loose parts of its territory. The upside is that it has a far better chance of keeping the territory it still has.
