The US can't prevent regional conflicts. Getting involved just helps them to spiral out of control and simultaneously puts America's own neck on the line. If there were actually a situation where a so-called adversary presented a legitimate threat to the US if left alone, it might be a different debate, but that hasn't been the case for many years. None of the states that the US is currently fighting in could hope to threaten it militarily in their wildest dreams. Iran, for example, which we are supposed to be so frightened of, has 1/45th the gdp and roughy 1/100th the military budget of the US. The US could cut its military budget by half and go into full defensive mode and still be completely untouchable by state actors, while removing the primary motivation for non-state attacks. True, the taliban might still kill people, just as plenty of regimes that the US supports like Saudi Arabia and Bahrain kill those it opposes. The US can't fix the world. It has enough problems of its own to worry about.
