The defense budget implosion (IX): The end of U.S. policy since WWII?

I don't automatically blog about every new report from CNAS,
but I am particularly struck by one
being issued this week about what future defense
budget cuts might be and what their effects might be. Bottom line: They say
that if the cuts go beyond about $550 billion, it will be difficult to carry
out the basic American policy since World War II of being engaged
internationally.

Lotsa people are rattling on these days about defense in an
age of austerity, but the report's authors -- retired Army Lt. Gen. David
Barno, Nora Bensahel, and Travis Sharp -- do a good job of doing more and
showing how the meat will come off the bones. They look at four levels of
budget cuts: About $350 billion, about $500 billion, about $650 billion, and
about $800 billion.

They don't quite say so, but they seem to favor the first
two -- which is significant, because they (at "the Obama Administration's
favorite think tank") are saying they could live with $500 billion in cuts. Go
much deeper than that, they say, and we start creeping toward isolationism.

The report bursts with provocative thoughts and suggestions.
Surprisingly for a study whose lead writer is a retired Army general, it favors
the Air Force and Navy over the Army and Marines. It wants to cut both ground
forces back to their pre-9/11 sizes. In the deeper cut scenarios, it basically
wants the Marines to get out of fixed-wing aviation, both lift and strike. It
also wants the Marines out of tanks, and wants the Army to reduce its number of
tanks, and to move a lot of the heavy Army force into the Reserves. It wants to
radically cut back on buying new weapons, but instead to keep alive R&D
until a new threat emerges.

The report also says we will be focusing less on the Middle
East in the coming years and more on the Asia/Pacific rim.   

I asked Barno about how the report is going down at the
Pentagon. "We did find the Army's reaction a bit more sparky than the other
services'," he said. No word yet on whether they are cutting off his pension.
Barno also said that operationally, the services are joint, but in budgeting,
they have failed to become so.  

Travis Sharp, who reminds me of John Hamre maybe 15 years
ago -- someone who really understands the interaction of budget and strategy --
commented that "the services are in a full defensive crouch" right now.
