President Franklin D. Roosevelt, aware that most publishers were opposed to him, issued a decree in 1943 that blocked all publishers and media executives from visits to combat areas; he put General George Marshall in charge of enforcement. The main target was Luce, who had long opposed Roosevelt. Historian Alan Brinkley argued the move was "badly mistaken" and said had Luce been allowed to travel, he would have been an enthusiastic cheerleader for American forces around the globe. However, stranded in New York City, Luce's frustration and anger expressed themselves in blatant partisanship.
