War criminal claims and our ignorance of history

Instapundit does us another public service by highlighting this Pajamas TV commentary about Jon Stewart claiming Truman was a war criminal:

Jon Stewart, War Criminals & The True Story of the Atomic Bombs.

As one of my friends wrote me after listening to it: "We were moved nearly to tears by this. What has happened to the world we knew?"

Our society is increasingly ignorant of history, which means we have lost touch with our roots and are subject more and more to whims of the moment that can only further endanger our liberty.
