The most upsetting thing is that the US is a leader in the world, and if they don't sign, then how do you expect to convince Russian and China and Iran, Pakistan, all these other countries, to sign? They simply won't. (The US government) feels it's against their constitutional right to bear arms, or they've said that it's needed in North and South Korea, on the border. I don't think any of these are good enough excuses for the damage.
