Unfortunately, at the moment, Ukraine lost more than 10% of territory under occupation, and other suffer from constant attacks on infrastructure, and sea export extremely limited, so we now very depend on grants from US and EU.
In foreseen future, if West will not give aviation and long range rockets, Ukraine will need revolutionary restructure of economy to survive.
For example, before war, Ukraine was one of the top food exporters, but now, with limited access to sea, have to use land routes, which are just add too much to cost of raw grain.
