Monday's White House visit by Hungarian Prime Minister Viktor Orbán — billed as an opportunity to cooperate on energy, trade and security issues — has left Washington divided.

The big picture: Hungary is a NATO member and potential partner in countering threats from Russia and China. Yet under Orbán, the country has witnessed democratic backsliding that presents its own threats to transatlantic security. The meeting with President Trump could undermine U.S. leadership on democratic values and human rights.
