More twittery from Shapiro. Once Hitler attacked the USSR--months before we entered the war--Britain was safe and Hitler's goose was cooked. The same is true of Auschwitz, which was liberated by the Red Army, which also inflicted 85% of all casualties on the Wehrmacht.
Buchanan has consistently advocated letting other countries do the fighting and dying whenever possible. For some strange reason, a desire to save American lives is seen as "unpatriotic" by those who think patriotism consists in volunteering (other) Americans to be the first to fight and die.
There are many reputable historians who would disagree with your assessment. In any case, when the Nazis declared war on the United States, we were obliged to come to the aid of the Allies.
Or worse, its labelled "retreat" or "anti" this or that.
The question that always has to be asked of those who attempt to blacken and smear others reputation for the temerity to disagree in good conscience and for expressly publicly virtuous reasons....is:

Not all conservatives go in lockstep. Witness Milton Friedman openly stating that going into Iraq was a mistake. I don't think that he should be drummed out of the Movement because he disagrees with us on that. But Shapiro is clearly not interested in a Big Tent that includes people on his right. Or actual open discussion, wherein we have to prove the viability of our positions, but instead vilify those who take strongly questioning stances that forces us to reprove the continuing basis for our assumptions.
