McDonald's has plainly rejected Burger King's proposal of creating the "McWhopper" in line with the upcoming annual "day of non-violence and ceasefire" on Sept. 21. Burger King announced the "truce" on Wednesday and proposed that the proceeds of the "McWhopper" will go to Peace One Day, a charity that creates awareness for world peace, according to a previous report by HNGN.

McDonald's CEO Steve Easterbrook agreed that the proposal is definitely for a good cause, but advised Burger King to create "something bigger to make a difference," CBS Los Angeles reported. He also added that their friendly competition should not be considered at par with the real ongoing war all over the world.
