An excellent piece, with much to think about, by Robert D. Kaplan in The American Interest, here.
I thought this paragraph especially interesting:
As American society grows more socially distant from its own military, American warrior consciousness is further intensifying within the combat arms community itself. The identities of each of the four armed services gradually grow less distinct. Rather than Army green, Air Force blue or Navy khaki, the slow but inexorable trend is toward purple, the color of jointness. The services have not yet lost their individual cultures, but operations both big and small are more and more integrated affairs. As each year goes by, interaction between the services deepens. The Air Force, with its once cushy, corporate ways, is becoming more hardened and austere like the Army, even as the Big Army becomes more small-unit oriented like the Marine Corps. The Big Navy, with its new emphasis on small ships to meet the demands of littoral combat, is becoming more unconventional and powered-down, also like the Marines.
Really? Inter-service rivalry fading away? That would be taking away half the fun of being in the military. Be interested to hear what serving military folk think of that.
[And with no disrespect at all to the U.S. Navy, can someone please tell me the point of wearing khaki at sea? In my own naval career we wore either Number Eights (light blue) or Number Twos (dark blue). Because the sea is blue, you see? Khaki? Just asking.]
