Zbigniew Brzezinski, who enthusiastically campaigned for U.S. President Barack Obama, has called on the president to shoot down Israeli planes if they attack Iran. “They have to fly over our airspace in Iraq. Are we just going to sit there and watch?” said the former national security advisor to former U.S. President Jimmy Carter in an interview with the Daily Beast. Brzezinski, who served in the Carter administration from 1977 to 1981, is currently a professor of American foreign policy at Johns Hopkins University's School of Advanced International Studies in Maryland.
