You thought badcppdev might be nervous about the modern equivalent of high kick marching competitions?
After badcppdev pointed out the US historically flew nuclear armed bombers to the borders of the USSR 24 hours a day? Including with the deliberate goal of escalating the nuclear threat to the Soviet Union, in order to improve America' position at the negotiating table?
Your statement "US jets intercept and turn them around" is incorrect - these flights are not turned around.
"High kick marching competitions" are not training exercises. Nor are they surveillance operations.
Reread my comment.
'Not a concern' is certainly what I would consider high kick marching competitions between guardstations
