JSF, in today's world in the west, you are correct. 60 odd years ago we employed rather more robust ROE in Malaya, Kenya, Aden etc. Russia may be operating as 70-80 years ago against a foe using rules from 700-800 ago.
Turning the other cheek may be Christian, but robust Christianity may be what is needed.
I see the media is now saying Putin-Assad is a least bad option.
