The issue with any negotiated settlement is that how do you trust Russia to hold up its end of the bargain after 2014? They've shown that international agreements mean sweet F.A. to them if it gets in the way of their goals.

The only way we get out of this in the long term to push Russia out of Ukraine, and force an unconditional Russian surrender. That means taking back the Donbas region; that means taking back Crimea.
