Roberts is a critic of Israel, calling Gaza "the world's largest concentration camp" populated by people who were "driven out of Palestine so that Israel could steal their land." Roberts has been a critic of both Democratic and Republican administrations. Although Roberts praised Ronald Reagan, he has compared supporters of George W. Bush to "brownshirts with the same low intelligence and morals as Hitler's enthusiastic supporters." He has opposed the War on Drugs and the War on Terror stating it has "made widows and orphans of millions of Muslims". He believes the official explanation for the events on 9/11 is a "scientific impossibility".
