Initially all these entanglements seem to have some noble purpose. American involvement just delays and prevents the locals from reaching their own consensus. BTW in case you hadn’t noticed oil producers are desperate and will remain desperate to sell their oil to anyone with hard currency or they starve.
Deployed, brave Americans die far from home and make the ultimate sacrifice for no good purpose. Sadly they are forgotten by most. Who remembers the dead from the USS Liberty, the USS Cole or the dead in Iraq and Afghanistan?
