Hyperbole. He is old enough to have seen Cambodia, Somalia, Algeria, various points west in Africa. It's not the worst of his lifetime even. I can sympathize with his pain but war is a mess which requires more than blind reactions and soft hearts. He must chose which side of this war he prefers to win to have any credibility, speaking for myself.
For me, at minimum, he must show a hard heart towards whoever it is he wants us to kill for credibility on policy. No mealy mouthing around about "doing something", he must name the people he wants us to kill for him just to sit at that table. He will not like the siege of Damascus, trust me.
He's a Doctor..Doctors dont care which side wins...nice deflection attempt.MSF treat both/all sides...bless their bravery and ethics
NGS is a doctor
