Pretty amazing what is available to the public now when it comes to satellite imagery.

The adults are talking deconfliction - I get it. Putin is now in the East Med bare chested on a camel, Assad is wiping out his own people - my head goes back to the Band of Brothers episode "why we fight". Emotional vs analytical response. I definitely did not graduate from the Kennedy School.
