Daniel Pipes explains the history and contemporary threat of this unlikely alliance, and concludes:
The burgeoning alliance of Western leftists and Islamists ranks as one of today's most disturbing political developments, one that impedes the West's efforts to protect itself. When Stalin and Hitler made their infamous pact in 1939, the Red-Brown alliance posed a mortal danger to the West and, indeed, to civilization itself. Less dramatically but no less certainly, the coalition today poses the same threat. As seven decades ago, this one must be exposed, rejected, resisted, and defeated.
