Russian didn't do anything yet its a humiliation of a great military power by a tiny jihadi country operates a small fleet of f 16 and F 5.
This is the perfect time to show the claimed superiority of SU 30SM and Mig 29/35 over puny f 16s of furks.
I would not take this as a humiliation.
I think many NATO members are saying this behind the scenes that Erdogan over-reacted. This makes sense if British propaganda outlet BBC publishes an OP-ed saying the same.
It was Turkey that first shot down the air-craft, and that it crashed inside Syria puts Turkey in a difficult position.
Now, with S-400, we have a virtual no-fly zone within the regions covered by S-400.
This actually gave Russia more power and operational freedom.
