FYI the Nazis killed about the same amount of Jews as the population of Israel is today.
Did the USA mass-murder Japs on U.S. soil? Without a war? Naaa,,,and the comparison is tasteless at best...
Anyway, getting back to FDR and the depression, it is correct that unemployment wasn't "solved" before America had to mobilize. Now bear in mind that the army brings no economical benefit, you could just as well mobilize the unemployed into doing something useful, since the govt pays for the army anyway....
So it's the same thing really, - the need for mobilization due to war solved the matter basically in the same way as FDR is being critizised for....if you ever get it Lazer.....
