People are generally supportive of spending reductions for the Federal Government but always seem to come down as fierce opponents of reducing the spending that they depend on or like for ideological reasons.
To be true to the principles of fiscal conservatism you need to accept the need for reduced spending in the programs you favor in order to deny liberals any excuses for cutting their favored spending.
Secondly, America is using the wrong model for military planning. We're looking about the world and declaring we need a military of X size when we should instead be supporting a military which we can afford and then prioritizing how to pack maximum effectiveness into the budget constraints.
The yo-yo-ing of reducing the military and then expanding it and then reducing it after the last crisis is an asinine approach in that with every reduction we lose institutional knowledge and that can't be easily replaced by heavy recruiting in times of crisis.
The military is like insurance - it has to be maintained even when it's not being used so that it's ready to do its job when its called on to do the job.
That said, 550 Majors and 1,200 Captains, isn't some massive bloodletting. Sucks to be them, just like it sucked to be a janitor or accountant at Enron when it got liquidated. People lose their jobs, families suffer the hit, it happens everywhere and the military shouldn't be immune.
Lastly, I'd love to get my hands on all these personnel records for I wouldn't be surprised if Obama's minions have politicized the selection procedures in their bid to Leftify society's principal institution which still upholds conservative values. A political purge of junior officers disguised as a budgetary force reduction is exactly what Obama and his vultures do - they inject politics into every god damned thing.
