SO what?
Here's the thing. The Germans and Italians, besides being much larger ethnic groups, weren't the ones who bombed Pearl Harbor.
The very fact Trump can propel himself to the top of the GOP heap playing on fears of Mexicans and Muslims today gives you an idea of what FDR was dealing with in 1942. People were damned scared. the looked out at that big Pacific Ocean and for all they knew, a Japanese Battleship could show up off the coast and start shelling them.
We didn't slaughter the Japanese. We relocated them out of a possible war zone, and most of them were released within a year.
Y'all need to quit whining about it. Other ethnicities have much more valid complaints.
What's your favorite thing about FDR?
Putting Americans with slanted eyes in concentration camps?
Inviting the 1936 Olympics team to the White House while telling Jessie Owens to stay home because he is black?
Gutting the military so much 3 nations declared war on us?
Sending Jews who fled Hitler back to Europe?
Appointing a KKK member to the Supreme Court?
"Gutting the military"
See here is the thing about you anti-FDR nutjobs. There are legitimate issues to attack FDR for- but then you just go all stupid, and reflect that it isn't really about FDR- it is because you dislike his policies.
After World War 1, the United States underwent a rapid demilitarization. In the 1930's, after Roosevelt came to power, there was at first a gradual build up the United States military- and then a rush starting in 1939 as Roosevelt(often at odds with Congress) pushed to build our military up to deal with the increasing threat from Germany, Italy and Japan.
WWII: Mobilization
And Japan didn't attack the United States because they thought our military was too weak- it was the other way around.
