The problem I've got with that...
...is that it would create a Muslim Diaspora.
Now, the Jewish Diaspora was a bunch of disposessed people who believed they got kicked out because God was punishing them, and therefore it was all their fault. AFAIK, they weren't exactly known for acts of terrorism in their time, rather just wandering around and asking God why He hated them so much.
Muslim extremists, OTOH, have a penchant for blowing stuff up. Lock 'em up in their own countries, not so bad. Blow up their countries, and suddenly they'll all be migrating all over the world - and blowing shit up in the countries they end up in.
No, I think I'd rather keep as many of the extremists in their country of origin, thank you very much.
