Any military is only as strong as the leadership responsible for unleashing its power.
With Mr. Mom Jeans in charge, fighting and winning wars is no longer a priority. The implementation of social change in the ranks is the order of the day.
The painful lessons of WWII taught us that, while battles can be won on the ground, wars are won by controlling the sky.
The people who realized that we would be better off with our current military structure, came to their conclusions by a trial by fire, not an academic paper.
Putin has shown the world rather conclusively that we are not quite as secure as we thought we were. I would be hesitant to leave the lessons of the past behind. Our military struggles since WWII have more to do with political failings than military failings.
Maybe this academics next paper can be on, just what kind of Mom Jeans our pre_sent should wear...
Depending on the reports, it showed the opposite. We sent waves and waves of bombers into hell, and Germany kept making tanks and guns till we over ran the factories.
In Japan, we would bomb and shell all day and night, and then we still had to send in the Marines to clear an island. Now air power has a role, a big role, but at the end of the day it is some guy with rifle that will solve the problem.
