The two leaders shared a border for six years, but former Mexico President Vicente Fox gives a tough assessment on President Bush in a new book out next month, according to U.S. News and World Report.

In “Revolution of Hope,” set to hit book stores October 4, Fox calls Bush “the cockiest guy I have ever met in my life,” and is sharply critical of the president’s Iraq policy and his immigration stance, according to the magazine.

Though he describes warm relations with Bush, Fox in the book also calls the president’s Spanish skills “grade’school” level and says, “I can’t honestly say that I had ever seen George W. Bush getting to the White House.”
