Former Israeli Ambassador to the United States Ron Dermer has joined the Jewish Institute for National Security of America (JINSA), the Washington, D.C.-based think tank announced on Tuesday.

Dermer, a longtime adviser to former Israeli Prime Minister Benjamin Netanyahu, is assuming the role of distinguished fellow at JINSA’s Gemunder Center for Defense and Strategy.

“Like Israel, JINSA punches well beyond its weight,” said Dermer. “It is an invaluable resource in both thinking about the strategic challenges facing the United States and Israel, and in crafting policies that can meet those challenges.”

Calling Dermer a “real mensch,” a “longtime friend” and “one of the leading foreign-policy minds and practitioners of his generation,” Makovsky said that “Ron will help make JINSA an even more important resource in Washington and Jerusalem, and in the policy debate across the United States.”

A native of Miami Beach, Fla., Dermer earned a degree in finance and management from the Wharton School of Business at the University of Pennsylvania and a degree in philosophy, politics and economics (PPE) from Oxford University. A former columnist for The Jerusalem Post, he co-authored with Natan Sharansky the best-selling 2004 book, The Case for Democracy: The Power of Freedom to Overcome Tyranny and Terror.

From 2005 to 2008, he served as Israel’s minister of economic affairs in the United States, and from 2009 to 2013 as senior adviser to Netanyahu. He began his nearly eight-year stint as Israel’s ambassador to the United States in October 2013.
