Good start, Broseph. The problem I feel is that it's too easy. Maybe introducing more atoms or a homing in feature on this one atom maybe? Still great work, keep it up!
I agree that the usa saved our assses but that's not to say that Britain and the other allied countries didn't do our bit. The Battle of Britain and the war in North Africa were mainly us. But i do admit without the US we would be speaking German.
