Well, I am not going to discuss the evident fact of Russia being resurgent; I'm rather into another evident fact: this is an insufferable event for some of the big guys around there, and Philip Breedlove is not an exception.
The very idea of bringing back U-2 for surveillance over Russia sounds as kind of a mental diagnosis to a formerly brave US fighter pilot and presently NATO supreme allied commander, who is to step down this spring.
56 year ago, on May 1, 1960 a U-2 did a great service in breaking US-USSR relations; Gary Powers did not commit suicide... Surely, for the US military those were good old times and bright hopes; a great war seemed to be round the corner. Luckily, then, in the sixties, big guys succeeded to overcome all crises and kept the strategic peace till now (I am not talking about local wars; those bloodsheds did not threaten the very existence of life on Earth).
Now, in 2016, the Breedlove's idea is not only desperately outdated; it puts under question the very ability of the high-ranked military to perceive reality adequately.
