Inertia in the U.S. military

This is where U.S troops were stationed abroad in 1951, 1986, and 2019. Things haven’t really changed in 70 years:

Rather than adjust grand strategy to take into account new realities, the dominant force has been inertia. The middle of the twentieth century brought America into certain countries, and it just stayed there and later invented reasons why doing so made sense.

That’s from Richard Hanania’s summary of his new book, Public Choice Theory and the Illusion of Grand Strategy: How Generals, Weapons Manufacturers, and Foreign Governments Shape American Foreign Policy. It appears to argue that American foreign policy isn’t very strategic, which checks out.
