Russian Airlines $12 Billion Disaster as Sanctions Force Russia into Plane Stripping & Subsidies
The war will end faster if either side gets to a point where the economic damage down by the war becomes impossible to live with.
IMO Putin has Plan A - do a deal the freeze the current boarders, end economic sanctions and rebuild for round 2. Putin doesn't have a Plan B, I am far from convinced that Russia can last much longer than another year. IMO Russia being able the sustain the war for 5 years is a total fantasy..
Very few in the west understand how weak vulnerable and prone to a sudden collapse Russia is. Luckily I think the Ukrainians understand, and they know while it might be tough for a while, if they hang in long enough, one day Russia will collapse, or there will be a change of leadership.
Russian public support for the war is still strong, but the full economic effect of sanctions, and the financial and human cost of the war haven't yet fully played out and been well understood.
Ukrainians don't really have an option for them losing is not an option, the current boarders are not an option.
My advice to Ukraine would be, don't worry too much about taking territory, just keep destroying Russian assets, but they do have an urgent need to liberate their people, which I understand and respect.
I hope I am not posting in this thread this time next year...
