　　President Bush spent the past four years snubbing and otherwise alienating his supposed amigo, Mexican President Vicente Fox, because Mexico didn’t back Bush’s invasion of Iraq.

　　So Bush’s critics in this hemisphere find it fitting that he’s now knee-deep in a policy mess over illegal Mexican immigration into the U.S., looking to Fox for any help he can provide. But when Bush, Fox and Canadian Prime Minister Stephen Harper meet today in Cancún to discuss the continent’s dysfunctional immigration situation, they might consider that one solution lies not so much in guest-worker programs or a 2,000-mile-long border fence, but in trade—namely, a revision of NAFTA, the North American Free Trade Agreement.
