I know a way for North Korea halt their Thermonuclear weapons and ICBM programs. Why didn't anything think of this?
Can you imagine if Russia, China and North Korea decides to go right outside U.S border and start threatening us and practising their drill for one day to invade us, no one likes that.
Can you imagine if a bunch of gun holding gangster outside your house day and night always looking to smash down your door and attack you? Of course you would buy weapons.
