I presume, they continue to count on US support on the assumption that a Europe that is tied up with Russia or weakened by Russia is not advantageous to the US. A dangerous assumption IMO.The US has been bankrolling and giving the most military aid of anyone. They have given huge support. But the US isn't endless. The US has an election coming up, and Trump says he is going to end the war. I doubt he means escalating it, or increasing support. It is quite probably the opposite.
If anything this last 3 months of shown, breaking down Russian defences is going to take far more than what UKR has right now.All IMO. I know my perspective seems to upset people. I may be very wrong, but I hope this perspective is accepted in the way its offered. If I was in Europe I would be stocking up on food and supplies. 2024 isn't far away.. I don't see a Ukraine winning a strategic victory by 2024.
The first batch is Ukrainian F-16 pilots won't be ready till 2024 if reports are to be believed and it is also naive to assume that those F-16 will make an immediate impact. Air power has always been a system of systems fight, and the same can be said of western combined arms operations. We are seeing the limits of that adoption here, which has basically degenerated into a 21st century version of WWI.
