All of the wars we are now involved in-- Syria, Iraq, Somalia/Djibouti, Yemen, and Afghanistan have all kinds of entanglements with different groups and different countries involved in the fighting. In Syria, the Kurds are among our best troops but they are enemies of Turkey and include some radical elements. We need Turkey to keep our airbase there. Turkey is supporting Yemen while we are supporting the Saudi's while we have a major facility in Yemen with 10,000 US personnel. Syria is incredibly complex. Can we ever pull out of any of these wars? We can, but it is quite likely that unless there is political stability we will be back-- look at Afghanistan and Iraq. On top of that Russia seeking air bases, and a strong role in the Middle East. In Somalia in Africa, the fighting is picking up again. We have sent troops to support the Mohamed Abdullah Farmajo regime, but we need more there soon.
