I don't see that happening any time soon and, if it weren't for the need to balance the US out a bit, I can't say I mind... We don't need soldiers dying in far away deserts or jungles. I'm pretty happy as it is, thank you very much. So we don't have the power and/or will to support dubious rebel groups, kick out evil dictators that don't see it our way and tell other nations they should comply with our wishes or get trashed. I can live with that.
