It may surprise you but Russia is not winning. It has been exhausting itself for no measurable benefit, at the cost for US taxpayers of roughly a coffee per day.

Up to now, Ukraine has never received the support it would need to win, just enough not to lose. Weapons deliveries been too little, too late, making the war longer and bloodier than it needs to be. In the meantime domestic production has increased to the point Ukraine covers 30% of its needs.

Russia has lost other wars, it can and should lose this one.

The best plan to prevent Russia from winning would be to cut off Russia's oil revenue. Fossil fuel exports are the only way that Russia can sustain their war effort. First, other European countries need to get serious and stop buying from Russia. Second, give Ukraine enough long range missiles to wreck Russia's fossil fuel infrastructure: pipelines, tank farms, refineries, ports, etc. Russia was heavily dependent on foreign technical experts to maintain that infrastructure and has little capacity to do so on their own.

This can be done with very little US funding. And sharing intelligence with Ukraine literally costs us nothing.

just because it hasnt worked so far doesnt mean it won't work. the time horizon matters. is russia gonna give up in 10 years? this is a bad plan. in 1 year? maybe not so much.

Hold the line, stop the oil tankers.
