I’m pleased that Andy McCarthy mentioned David Horowitz’s book Unholy Alliance, below. My impression is that this is an under-read and under-known book. (I could be wrong on this.) It’s a superb book. I reviewed it when it was released, five years ago. (Find that review here.) The subject may seem extreme — an alliance between the Left and the jihadists, really? Are you sure you aren’t stretching? And the cover seemed a little fringy: a stick of dynamite with the fuse lit, as I recall.

But what an impressive book — devastating, really. Horowitz is known as a flamethrower, but this book is cool and measured, marshaling evidence into something irrefutable, or at least unignorable. I did not think the same way about current politics — the war atmosphere — again.
