Will/would be able to

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.

Solution 1:

They generally mean the same thing, however "would be" implies that it is presumed based on the speaker's understanding, not necessarily acknowledged fact. For example, "would be" has a similar meaning to me as "There's a hospital in the US – I believe that they should be able to treat this." https://www.merriam-webster.com/dictionary/would
