On January 27, President Donald Trump signed a National Security Presidential Memorandum on rebuilding America’s armed forces that calls for a new Ballistic Missile Defense Review. The review is tasked to “identify ways of strengthening missile-defense capabilities, rebalancing homeland and theater defense priorities, and highlighting priority funding areas.”

A previous draft White House memorandum included language similar to congressional requests mandating a new “Missile Defeat Defense Review” to “determine homeland and theater missile defense priorities; identify of ways to strengthen ballistic missile defense, cruise missile defense, and hypersonic weapon defense; integrate missile defense planning into broader strategic planning; and identify priority funding areas.”
