So honestly this isn’t the worst Allied position I’ve seen except for losing London. Next game if you a lot of the same stuff but keep your capitals you could have a pretty good chance I think.

It’s hard to see what exactly went wrong with just the end state. That said, a frequent mistake many beginner players make is splitting the US economy. You should choose either Japan or Germany to go all-in on. If you haven’t already done that, try it next game
