How the World Views Trump

How would the rest of world react if America elects Donald Trump as its next president? President Obama has said that the world leaders are “rattled” by the prospect of a Trump presidency.
They are paying very close attention to this election. I think it's fair to say they are surprised by the Republican nominee. They are not sure how seriously to take some of his pronouncements. — President Barack Obama

Europe does not like Trump

A Pew Research Center poll revealed that people across Europe do not believe that Donald Trump would do a good job of managing world affairs. According to the survey, some 85% of Europeans do not think Donald Trump would make a good president. In Japan, 82% feel that doubtful about Mr. Trump. At the same time, Europeans like President Obama, with 77% giving the President a favorable rating.
Mr. Trump has called US foreign policy "a complete and total disaster", saying that it has "no vision, no purpose, no direction and no strategy". His proposals alternate between a more robust pursuit of US interests on the international stage while avoiding costly engagements or entanglements. — BBC

America First

Trump’s campaign theme is “America First” and Mr. Trump would approach foreign affairs with the same attitude. Trump has said that the “U.S. has become a dumping ground for everybody else’s problems.” Trump has stated that he feels other countries are not paying their fair share of the costs for NATO and it's an unfair burden on the American taxpayers.
I'm going to renegotiate some of our military costs because we protect South Korea. We protect Germany. We protect some of the wealthiest countries in the world, Saudi Arabia. We protect everybody and we don't get reimbursement. We lose on everything, so we're going to negotiate and renegotiate trade deals, military deals, many other deals that's going to get the cost down for running our country very significantly. — Donald Trump

Mexican President dislikes Trump

Most leaders of foreign countries have avoided expressing their view of Mr. Trump. However, one who has not been shy about expressing his views has been Mexican President Pena Nieto. The Washington Post reported that last March Mr. Neito compared Trump to Hitler and Mussolini, “That’s how Mussolini got in, that’s how Hitler got in. They took advantage of a situation, a problem.”
Vox put together a list of some comments from world leaders:
"Mr Trump is so stupid, my God!" said Paris Mayor Anne Hidalgo.
"He changes opinions like the rest of us change underwear." Danish Foreign Minister Kristian Jensen.
"His discourse is so dumb, so basic," said Ecuadorian President Rafael Correa.
"I can only hope that the election campaign in the USA does not lack the perception of reality," said Germany's Foreign Minister Frank-Walter Steinmeier referring to the "America first" slogan.
"Whether Donald Trump, Marine le Pen or Geert Wilders — all these right-wing populists are not only a threat to peace and social cohesion, but also to economic development," Germany's Vice Chancellor Sigmar Gabriel said.
Some European’s feel that if Trump is elected it would embolden those who would want the EU to toughen its policies on immigration, and could lead to more countries choosing to follow Great Britain in exiting the EU.

Trump and Putin

Much has been made of Trump’s comments about Vladimir Putin. “I believe I’ll get along fine with Putin,” Trump said on ‘This Week.’ NBC News characterized the relationship with Putin as a “bad bromance between two alpha males.”
There is no record that Trump and Putin have ever met nor spoken to one another. Putin and President Obama openly dislike each other. Hillary Clinton advocated for a “Russian reset” in 2009, while she was Secretary of State, but her relationship over the past six years with the Russian leader has been acrimonious. Putin has said that Russia would work with whomever the U.S. elects as President, but there is little doubt that he would prefer the unknown Trump to the known Clinton.

Suspicion that Russia hacked Clinton emails

There has been a suspicion that Russia has been behind at least some of the hacked leaks of Hillary Clinton’s emails, but so far there has been no concrete proof of Russian involvement.
Donald Trump’s audience is the American voters, not the rest of the world. In some parts of the country, his message of a strong and more isolated America resonates with voters. U.S. foreign policy under Donald Trump would most certainly be different than the foreign policy of Hillary Clinton. In just over a month, American voters will decide which version they prefer, and the rest of the world will be watching with more than a casual interest.
