President Obama spoke out against Donald Trump at the G-7 summit in Japan on Thursday, saying that world leaders are shaken by the presumptive GOP nominee's campaign.
"They're rattled by him and for good reason," Obama said. "Because a lot of the proposals that he's made display either ignorance of world affairs or a cavalier attitude or an interest in getting tweets and headlines instead of actually thinking through what is required to keep America safe."
"They are surprised by him, not sure how to take some of his pronouncements," the president continued, adding that the world is watching the U.S. presidential election and Trump's campaign.
"The U.S. is ... at the heart of the international order and even those countries that are critical of us ... know that ultimately things don't hold together so well if the U.S. isn't making good decisions. They count on us to provide stability when making global decisions."

Trump campaign spokeswoman Katrina Pierson responded on CNN, saying, "Sure they're rattled. Because the gravy train ends if Mr. Trump becomes president ... Mr. Trump's most important concern are the people here."
The president's continued criticism of Trump comes after the billionaire businessman lashed out at several leading Republicans, including Mitt Romney, at a rally in Anaheim, California, on Wednesday.
Trump said Romney "walks like a penguin" and added, "Poor Mitt Romney. I have a store that's worth more money than he is."
"I understand losers. You can make a lot of money with losers," Trump continued of the 2012 Republican nominee for president. "The last election should have been won, except Romney choked like a dog. He's a choker."
The mogul also slammed former Texas Gov. Rick Perry for saying "the worst things about me" and took yet another shot at "low-energy" Jeb Bush, predicting that the Florida governor will eventually endorse Trump when he gets "a burst of energy."
Trump also used his go-to nicknames for Democratic hopeful Bernie Sanders ("Crazy Bernie") and Massachusetts Sen. Elizabeth Warren ("Pocahontas," a reference to her claims of Native American heritage).
He went on to criticize Democratic front-runner Hillary Clinton, saying, "She doesn't have the temperament to be president. She's got bad judgment â€¦ If you look at the war in Iraq, if you look at what she did with Libya, which was a total catastrophe."
But a new Bloomberg poll of working-class voters in Michigan, Ohio, Pennsylvania and Wisconsin shows that Clinton is leading Trump by seven points (46-39). Fifty-seven percent of those polled said they were "deeply troubled" that Trump proposed tax cuts for those making more than $1 million a year. And 60 percent of voters said they're bothered "a lot" by Trump's use of words like "pig," "slob," "bimbo," and other crude comments to describe women.
Despite the many insults he lobbed at his rally Wednesday night, Trump insisted that he was a "nice person" who "loves people."
But, he added, "If I was nice to everybody, I wouldn't be here today. I'd be watching television right now."
