Poorly prepared in the big picture. I think they well prepared for what they planned to do.
You answered your own question. They could have sent more fighters physically, but did they have the budget to?
It's pretty insane to think about it. The term "K-shaped economy" was recently coined, acknowledging that people who are already economically disadvantaged are falling even further behind. Yet the president can blindly charge into an expensive war, with shockwaves that are further making the cost of living even more difficult. The wealthy can mitigate some of the everyday shock with expensive electric cars, but affordable models were turfed due to government policy, and imports banned by the previous administration. Still, we are told this is democracy at work, and to look at the CCP who are telling young people to "eat bitterness", life is so much better in the USA!
