I disagree a bit with what most are posting here, since I think he had a post-Pearl Harbor opportunity to use the war as an excuse to "temporarily" suspend segregation as a necessary step in the war effort, particularly if he played it off against the prevailing sexism of the day and said the alternative was to make women work in factories. This sort of reduces opposition to the level of "if you support segregation now, you're helping the Japs and Nazis and making women do dangerous factory work." The impetus for this would have been to keep skilled and experienced white factory workers at home rather than in the service, with black soldiers taking their place in an integrated Armed Forces and, to a lesser extent, in factories doing defense work.
Now, having said this, that's in hindsight and not in the pressure of the day circa 1942, where it would have been seen as a risky move that threatened domestic unity and thus the war effort itself if the resistance were too great.
Again, how does he answer the question "Why not just make segregated All-Black units with white officers? Then we'll avoid intera-unit tensions and be able to better tailor conditions for the different racial needs ect.?"
Desegrigation is not the only alternative to banning. There's the whole "separate but 'equal' " field one must contend with
