Based on his warped worldview, he contended that nothing intrinsic binds America’s allies together. He has publicly vacillated about whether or not the United States is prepared to defend Taiwan’s autonomy from China. The United States has signaled that it will be withdrawing units assigned to defend Europe (and has incoherently canceled and uncanceled existing deployments). It is true that many of America’s allies to some extent forgot that lesson at some point and coasted on American power—a decision that was both morally wrong and strategically foolish. If America’s allies can’t count on U.S. support, they’ll seek it elsewhere.
