"No" ??? What fact in my post, or in the linked LIFE magazine article, do you dispute?
Read the article. Look up the executive order for yourself, if you like. I have done so.
FDR ended voluntary enlistment. That is a fact. You can speculate all you like about the reasons for it ... it's still a more or less free country ... but I'm not addressing that.
No to your context, FDR had to go to a draft to fill the ground forces.
Enlistments weren’t cutting it.
My uncle, a WWII vet, told me that from 1943 on their were no more enlistments. If you tried to enlist you were told that you would go into the service when you were told to report. My uncle wanted to join the navy, but he was drafted into the army.
