The war angle is supported by heightened wariness in NATO re Russian bombers in the air. NATO is certainly watching.

"Two Russian Tu-160 Blackjack strategic bombers that carried out a routine patrol mission over the Arctic and Atlantic Oceans were shadowed by four NATO fighters, the Defense Ministry said on Friday.

Spokesman Lt. Col. Vladimir Drik said the bombers spent about 11 hours in the air on Thursday and were "accompanied" by two NATO F-16 Fighting Falcons of the Norwegian Air Force and two RAF Tornados.

This is thought to be the first time Russian strategic bombers have been followed by such a large number of NATO jets."
