It depends on what happens. If Europe/US just shrugs and moves onto the next thing after the war, which is probably the most likely outcome, then yeah. But there is a real chance that they try to go full Marshall Plan with the goal of weaponizing Ukraine. If so, then there's going to be a lot of money flowing about there with some big opportunities.
With what surplus resources? Europe seems to be suffering from some pretty catastrophic looking political blowback with groups like Reform, AfD and a host of similar-looking parties gaining popularity because people don't think their interests are being prioritised. The US has a Trumpism phenomenon that might be matched by a left-wing revolt (crazy policies waiting in the wings Mamdani prioritising New York over Israel. The gall of the man).
On paper the US is broke. I'm not sure about the Europe situation but I doubt they're doing well either the growth statistics I saw last were a joke. They're all struggling to even arm Ukraine for this war.
If I were a Ukrainian strategist I too would not count on some sort of vast infusion of resources appearing after the war. These are not the conditions of the Marshall Plan where Europe had massive economic potential and the US was the world's leading industrial superpower with wealth to spare.
