Buchanan’s “controversial” column is an echo of an argument advanced in certain Far-Right circles in the late 40s and 50s — the argument that we fought the wrong enemy in World War II. If you want to engage it seriously, the problem with it is that it falsely supposes we had a One From Column A, One From Column B choice in 1941 and could have picked confrontation with the Soviet Union rather than a war with Germany. The other problem with it should go without saying, so I won’t say it.
