Donald Trump's world and his ties to Germany, Scotland, Slovenia and more

(CNN)World leaders tend to stay out of U.S. presidential elections; they rarely comment on candidates yet even to receive their party's nomination.

But previous elections didn't feature Donald Trump, the man who during a presidential debate made an impassioned defense of his penis.
Mexican President Enrique Pena Nieto has said of Trump's campaign tactics: "That's how Mussolini got in, that's how Hitler got in."
British Prime Minister David Cameron denounced Trump's suggestion of a ban on Muslims entering the United States as "divisive, stupid and wrong."
    On the plus side, Russian President Vladimir Putin called Trump "an outstanding and talented personality."
    The irony is that Trump is a true man of the world: quite simply, other countries are essential to his businesses, his personal life, even his birth.
    It's time to visit the nations that have made The Donald such a unique American.
    C'mon, everyone, hop aboard Trump Air -- actually, it's probably best to find an alternative form of transportation -- and see the world Trump-style!
