Teddy Roosevelt...
...would probably have shot someone like Blum.
1960s liberals who seem to delight in projecting their own attitudes throughout American history might want to do a bit more research on people like Theodore Roosevelt. Pay special attention to his thinking during WWI.
The professional pacifists have, during the last three years, proved themselves the evil enemies of their country. They now advocate an inconclusive peace. In so doing they have shown themselves to be the spiritual heirs of the Tories who in the name of peace opposed Washington, and of the "Copperheads" who in the name of peace opposed Lincoln. We regard these men and women as traitors to the republic; we regard them as traitors to the great cause of justice and humanity. This war is a war for the vital interests of America. When we fight for America abroad we save our children from fighting for America at home beside their own ruined hearthstones.
Teddy Roosevelt, 1918
