What the British will do to end "the existience" of ISIS?

The thing is there are many extremists Britons in country who support ISIS. So they will act in case ISIS needs some support from the inside.

All these western countries have to wait till these extremists and fundamentalist gather in one place(caliphate). Then annihilate them.

Nothing.

Thanks to Bush's bullheadedness, the rest of the world is content to let the US deal with ISIS - a mess we're partially responsible for anyways.

Other nations have said they would fight...but only AFTER the US has committed ground troops.

So..guess where our soldiers are going to be spending Christmas this year?
