I am of the opinion that we should sell an unlimited amount of weapons to other countries, but all of them should be swords.
Matter of fact, I would LOVE to see a massive global stigma against the use of ranged weapons. I would like to see the stigma be so terrible that any country having ranged weapons would be invaded by 10,000 troops (armed with swords), along with 1,000s of sword tanks (tanks with HUGE swords on them).
It will never happen, but if we could somehow socially engineer a stigma against ranged weapons than wars would pretty much cease.
