Mitt Romney has delivered a lot of dishonest speeches in recent months, but Monday’s address on foreign policy may be the most mendacious yet. It was expected that he would distort President Obama into a caricature of Jimmy Carter. But it was astonishing to watch Romney spin a daydream of himself as some latter-day George Marshall, bringing peace, prosperity, and hope to a chaotic world—this from a man who couldn’t drop in on the London Olympics without alienating our closest ally and turning himself into a transcontinental laughingstock.
