Trump's Attack On London Mayor Isn't New: 5 Times He Insulted World Leaders

President Donald Trump took to Twitter Monday to again criticize London Mayor Sadiq Khan for how he responded to Saturday's terror attacks in London. Trump had already attacked Kahn once on Twitter only hours after seven people were killed in a terror plot that involved using a truck to run people over on London Bridge and a subsequent knife attack at a nearby market.

Trump’s twitter attacks take out of context a quote the mayor said about how Londoners shouldn’t be concerned about seeing an increased security presence. Khan, however, isn’t the first foreign leader to feel Trump’s insults.

1. Chancellor Angela Merkel and Germany:

In May, Trump insulted Merkel and all of Germany because of their trade policy. “The Germans are bad, very bad. See the millions of cars they sell in the U.S., terrible. We will stop this,” said Trump in an interview with German Magazine Der Spiegel.

2. North Atlantic Treaty Organization (NATO):

At the end of his first foreign trip in May, which saw Trump travel through Europe and the Middle East, Trump scolded European leaders at a NATO meeting in a speech. “NATO members must finally contribute their fair share and meet their financial obligations … this is not fair to the people and taxpayers of the United States, and many of these nations owe massive amounts of money from past years and not paying in those past years,” said Trump. In the past Trump has called NATO an “obsolete” organization.

3. Mexican President Enrique Peña Nieto:

In January, Trump escalated his feud with Mexican President Enrique Peña Nieto over which country will pay for his proposed border wall along the U.S.-Mexico border, and a canceled visit by Nieto. “Most illegal immigration is coming from our southern border. I’ve said many times that the American people will not pay for the wall. And I’ve made that clear to the government of Mexico,” Trump said in remarks to congressional Republicans during their annual retreat. “To that end, the president of Mexico and myself have agreed to cancel our planned meeting scheduled for next week. Unless Mexico is going to treat the United States fairly, with respect, such a meeting would be fruitless and I want to go a different route. We have no choice.”

4. Australian Prime Minister Malcolm Trumbull:

In his first phone call with Australian Prime Minister Malcolm Trumbull in January, Trump got upset with the leader over a deal Trumbull worked out with former President Barack Obama. The deal would send one thousand, two hundred and fifty refugees to the United States from an Australian detention center. Trump called it “the worst deal ever.”

5. Hand Games:

Trump’s insults aren’t always in tweets and remarks, sometimes they are physical. Despite praising the leader later, Donald Trump shook Prime Minister Shinzo Abe’s hand for a full 19 seconds in an awkward exchange. Merkel didn’t get the pleasure of a handshake when she first met Trump, despite the call to do so by assembled press photographers. French President picked up on Trump’s handshake games and reversed some of Trump’s power tricks back on him when they first met.

The world leader who might best know to stay out of Trump’s way though, is Montenegro Prime Minister Dusko Markovic.
