WASHINGTON (AP) — As Iraq edges toward chaos, Joe Biden is having a quiet I-told-you-so moment.

In 2006, Biden was a senator from Delaware gearing up for a presidential campaign when he proposed that Iraq be divided into three semi-independent regions for Shiites, Sunnis and Kurds. Follow his plan, he said, and U.S. troops could be out by early 2008. Ignore it, he warned, and Iraq would devolve into sectarian conflict that could destabilize the whole region.
