I'm glad everyone doesn't think like you do, this world would be a disaster if they did [spoiler]what if America was ravished by an unfortunate natural disaster and we lost all of our infrastructure? What if when that happened our allies/other counties were just like "eh, we have better things to do, they'll fix themselves"? That's not how it works. Countries don't just "sort themselves out" after a natural disaster without any aid [/spoiler]
