Can you imagine what the global reaction would be? I could imagine the RAF disintegrating ISIS, home and abroad.
That is an enormous question mark. One would think that the British reaction would be swift, and most severe. But Cameron is not Churchill.
Churchill would have destroyed ISIS. But Cameron...perhaps a few punitive raids would have to do. And does today's Britain even have the resources to do more? At any rate, it is a terrible thing to consider.
The RAF does not possess a single bomber.
