There will always be policing in this world. If US dont get involved in policing than china or russia will start. thats the human nature so no matter what there will always be one ploicing country. The question is would you like to be live in a world where china or Russia is policing or US. For me my answer is clear. Yes we do have issue but its far much better that the option we have. And you may not like it but right now is the peaceful time to live in if you know all the history of human civlization.
