Leave the policing of the world to the United Nations

For too long, the United States has wasted money, resources, and lives fighting wars in foreign countries, causing death and destruction, for no one's benefit besides radical militant groups and oil tycoons. The more we invade Middle Eastern countries, the more people there hate us, and for good reason. The number of children killed as collateral damage in drone strikes is disgusting, and countries who wish to choose their own paths have been strong-armed into doing what we want them to do. I say we should stop wasting trillions of dollars that could be used to benefit Americans (via education, healthcare, infrastructure etc.) and allow the keeping of the peace in the world to be the responsibility of the United Nations, which was formed for that very reason.
