Well, we're about to find out whether or not McDonald's Peace Theory[1] is true or not.
> In Thomas L. Friedman's 1999 book The Lexus and the Olive Tree,[56] the following statement was presented: "No two countries that both had McDonald's had fought a war against each other since each got its McDonald's". He supported his belief, as a theory, by stating that when a country has reached an economic development where it has a middle class strong enough to support a McDonald's network, it would become a "McDonald's country", and will not be interested in fighting wars anymore.
