BTW, for those interested in details, it was emphasized along with the "main announcement" that not all the aircraft will be returned back to Russia. A certain minimum will remain. Somewhat a sqdrn of attack aircraft and some fighters to support them. The same for some helicopters. And of course S-400 and Pantzyr anti-aircraft ground systems will remain as well. It was also published in the (Russian) official press that if necessary it will be a matter of hours to return.
Just to avoid being blamed in inconsistency....
