Bing West on the Iraq War

Here's an absolutely fascinating video:
I'm particularly struck by similarities between the Iraq War and the U.S. Civil War. In the 19th Century campaign, the Union forces, though greatly outnumbering the Confederate forces of the South, were stuck in a quagmire for several years until Abraham Lincoln appointed Ulysses S. Grant as General in Chief. Something similar seems to have occurred with General David Petraeus' appointment in Iraq.
