Hoover Institution fellow Victor Davis Hanson discusses deterrence in terms of world affairs and especially after Obama.
Deterrence is a clear display of overwhelming military strength, and the real probability of being willing to use it, so it reminds would-be aggressors not to start stupid conflicts — given that the possibility of winning something through war is overshadowed by the risk of losing far more. A world where everyone knows the unspoken rules as well as the moral and material relative strength and weakness of the various nations is a safer place for all involved.
To restore the Western-inspired postwar order and hold chaos at bay, the next president will have to restore deterrence, both materially and psychologically. And that will be one difficult and dangerous endeavor — made worse by shrill attacks coming from those who have done so much to lose it. If the Obama administration cannot keep speak softly and carry a big stick, then at least it should keep quiet—and quit egging on those it cannot or will not deter.
