There isn’t anything to negotiate, it would merely be surrendering.
OK Russia, you have taken the best and richest parts of our nation and ports, can we stop now?
The problem is the West is intentionally prolonging the conflict to achieve it's own ends, including personal enrichment via graft and corruption and possibly setting the world up for a Chinese invasion Taiwan, while the Ukraine and it's people suffer the devastation of brutal warfare.
The longer the war goes on the more Russia will feel the need to gain from it's ill advised invasion and the longer the war the goes on the more the Ukrainians will have lost from the war and feel the need for more retribution from Russia that Russia will not accept.
Add in Russian mobilization and massive short term infusion of advanced weapons from the West to support Ukraine and we will see a serious escalation and widening of the conflict, which BTW, is happening on Ukrainian territory. God help us if the conflict widens to Russian territory.
Tanks and jets, if used properly, can generate leverage that brings about a cease fire and eventual negotiated settlement. The proposed tanks and jets are not likely to expel the Russians from the Ukraine and the strategy may backfire by forcing the Russians on the offensive before the Ukrainians can actually deploy their new assets.
The only option then is direct NATO intervention, which is where we are heading.
