Okay, so this is odd and actually pretty clever. But I don't know how effective thinking happy thoughts will bring about change. For Christians, I think we could make a difference by not always having to be "right" and living our faith instead of pointing the fingers at others. But then, maybe eating hamburgers is a better solution.
"In honor of Peace Day, September 21st, Burger King is inviting McDonald's to team up to create the McWhopper — a burger built for world peace. If they say yes, we’ll mark this ‘burger wars' ceasefire with a one day pop-up McWhopper shop in Atlanta on Peace Day, halfway between our two headquarters."
