My friend: I am ready to go to any country in the world if there's a treatment.
Me: There's a hospital in the US – they WOULD/WILL be able to treat this.
What's the difference between WOULD BE and WILL BE here? TIA. I know there are a lot of questions about will/would but most of them are about which one's more polite. And I don't think mine has anything to do with politeness.
