WE HAVE TWO covers this week. In most of the world we contemplate Donald Trump’s plans for the Pentagon. He recently declared that it would become a target for Elon Musk’s Department of Government Efficiency. The work could not be more important. Not since the Soviet Union launched Sputnik and built huge tank formations at the height of the cold war have America’s military vulnerabilities been so glaring. In the killing fields of Ukraine America is being out-innovated by drone designers; in the seas and skies off China it is losing its ability to deter a blockade or invasion of Taiwan. Pentagon angst is as old as the military-industrial complex, and it is hard to think that this administration will succeed where others have failed. But the hope is that it will. America’s security depends upon it.
