I know what you mean Mac. Its a massive problem, but holding talks & becoming friendly with each other is the cheapest option..
China, Russia, North Korea and the West all need to think what a war would mean. Each of us can kill the other so even if the UK was obliterated our Nuclear Submarines are still at sea about to kill them so no one will win and millions of good people that didnt want a war end up dead and the earth is contaminated with radiation for hundreds of years or more for any survivors..
