Mattis on Friday “underscored the U.S. commitment to Israel’s security and its qualitative military edge,” according to a readout of the meeting from the U.S. Department of Defense.

Mattis and Liberman discussed last week’s visit to Washington of Prime Minister Benjamin Netanyahu, as well as “other mutual defense and regional policy issues.”

The defense leaders “concluded the meeting agreeing to continue close collaboration and consultation on a range of bilateral defense activities and initiatives,” according to the readout.

A statement released by Liberman’s office said that the three central problems facing Israel and the U.S. are “Iran, Iran and Iran,” and that the two leaders agreed that that they must act with determination against Iran.

It is the first time that Mattis and Liberman have met in person.
