Whether or not President Trump strikes a nuclear deal at his summit with Kim Jong Un, the U.S. still needs to prepare for attacks on its homeland and abroad. China recently installed missile systems on artificial islands in the South China Sea, while economic backwaters like Russia and Iran invest heavily in missile tests and research. At least Congress is developing bipartisan support for missile defense.
The Senate this week is expected to vote on its version of the National Defense Authorization Act (NDAA), which the Armed Services Committee approved 25-2 in May. While missile defense can’t perfectly insulate the U.S. or its troops abroad, the new legislation includes notable improvements that would make America’s rivals think twice before striking.
The U.S. fields several missile-defense systems around the world, but each has its own radar. The Aegis Ballistic Missile Defense is deployed at sea and can bring down regional threats inside the atmosphere. The Ground-based Midcourse Defense (GMD) protects the U.S. homeland by targeting long-range missiles in space. But the systems don’t communicate and coordinate well.
