Purge and Counterpurge
I have problems with both guys' world views and would likely prefer a colicky baby to either one as a row-buddy on a long flight, but when David Frum and Justin Raimondo trade direct fire on the war, conservatism, and everything the results are entertaining, illuminating even. I think Raimondo has a good point that Frum weakens his case by not providing links to all the source material he cites. Enjoy, but take a flak jacket.
