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
