I'm all for having the strongest military in the world. However, excessive military intervention does not improve national security and can only do harm economically in the long run.
The post-Cold War era has seen a continuation of a long global trend toward greater peace and stability, lower rates of conflict, and zero great power wars. More peace and diminishing threats have merely enhanced the remarkable security already enjoyed by the US thanks to its geographic isolation, weak neighbors, unparalleled economic and military power. But America doesn’t act as if it is safe. Instead, we have a hyper-interventionist foreign policy.
