The last administration that had a ton of Jews in it was George W Bush's. They were the so-called "Neocons". To name the most prominent, but by no means all:

Richard Perle: One of the principle architects of the Iraq war, he was a close advisor to Sec of Defense Rumsfeld

Paul Wolfowitz: U.S. Deputy Secretary of Defense

Douglas Feith: Under Secretary of Defense for Policy

Scooter Libby: Chief of Staff to Vice President Dick Cheney, Assistant to the Vice President for National Security Affairs

David Frum: Primary speech writer to President George W. Bush

Dov Zakheim: Undersecretary of Defense and Comptroller

Elliot Abrams: Special Assistant to the President and Senior Director on the National Security Council for Near East and North African Affairs

Eliot Cohen: Senior Counselor to Secretary of State Condoleeza Rice

Marc Grossman: Under Secretary of State for Political Affairs

Josh Bolten: White House Chief of Staff



And of course, no list of war-mongering Jewish Neocons would be complete without the original war monger himself:

Henry Kissenger: Chairman of Committee reviewing 9-11 terrorists attacks, special counselor to President Bush and Vice President Cheney for the Iraq War
