Where's the real war?

Rumsfeld's Army is busily - and futilely - shooting at insurgents, but the supply of weapons and men seems endless. Does anyone know where the guns they all carry are coming from? Someone has to be selling the weapons to the Islams; it's usually the French, yet so far no one has thought of cutting off the supply.

I watched a WW II movie where the Brits bomb a heavy water factory and shipment. It made sense then, but now, nothing makes sense.
