I do not see any further "Invasions" I see terrorists attacking here and there putting pressure on relationships trying to open a wider conflict. I think the world knows we can come in and close up shop in any country in a few months at most. Granted we would leave a mess behind but countries like Syria ,Iran etc. know we will kill off the leaders. So I think we will enter into a cold war period for the next 10 years or so. Hitting terrorists bases hee and there and not making any freinds in the ME or politically elsewhere. I see the world divided like never before but paralized and politicised from dong much about it.
