No, you can't. This is literally the entire premise of crypto.

Firstly you can't just open a bank account in another country if you come from a place like Palestine. It's not that simple, or even potentially legal. And a bank isn't going to break the law on your behalf.

If a bank blows up because another country blows the shit of of yours, there is jack shit you can do. Or if the currency becomes worthless or ceases to exist because your country ceases to exist. Or the government just says "we need to take the money from the banks to find the war efforts, well pay you back when we're done".

It's an interesting example of a very, kind of surprising niche use case where a distributed trust less ledger is actually a better solution.
