Another War looming?

[Jace]

I guess it depends how many of the "jihadists" are actually serious and how many are just loudmouths on the internet?

I see that many western countries are cancelling the passports of potential extremists so they can't get to Syria or Iraq. Dunno why they don't wait till they leave the country and then cancel them, meaning they can't get back in, and therefore have to stay in the hellholes they have decided to go to, and not come back and cause trouble?
