Back in a 2007 Republican presidential primary debate, then-presidential candidate Ron Paul sought to educate fellow presidential candidate Rudy Giuliani and the American people about the concept of blowback. Paul did so after Giuliani claimed during the debate to be shocked to hear Paul’s “absurd” argument that people would attack Americans, such as in the attacks of September 11, 2001, in reaction to the US government’s interventions abroad. As Paul noted in reply, blowback is understood and taught by the Central Intelligence Agency and has occurred through American history, including with the 1979 taking hostage of Americans in Iran.

In a speech Wednesday in Greenville, North Carolina, President Donald Trump showed that, like Giuliani, he could use some education in regard to blowback. Among a series of criticisms of Rep. Ilhan Omar (D-MN) that Trump stated in the speech was that “Representative Omar blamed the United States for the terrorist attacks on our country, saying that terrorism is a reaction to our involvement in other people’s affairs.”

Maybe Trump could hit the books regarding the subject of blowback. After Paul’s debate dustup with Giuliani, Paul, in a press conference, discussed blowback further and offered a reading list that could help enlighten Giuliani regarding blowback and foreign policy. It could be helpful for Trump as well.
