I think that killing Osama Bin Laden, what the operation revealed about Pakistan, the dreary state of the U. S. economy, and a host of other forces won’t cause us to reduce our vast security spending much but are pretty likely to turn our attention in other directions. What directions? There are still a lot of China hawks in the Pentagon (and they’re really the only candidate for a near-peer competitor). Mexico’s problems are becoming increasingly concerning. Do the drug traffickers there really have tanks? Africa, maybe.
Everything but what we should be doing which IMO is standing down a bit.
