POINT/ COUNTERPOINT

Should the U.S. Exit the Open Skies Treaty?

In a move former CIA Director Michael Hayden called “insane,” President Donald Trump decided on May 21 to withdraw from a little-known arms control agreement called the Open Skies Treaty. This agreement, negotiated in the early 1990s between NATO and Warsaw Pact countries and brought into force in 2002, provides for cooperative aerial-monitoring flights over 34 member states.
