WASHINGTON: Democratic presidential front-runner Hillary Clinton is set to unleash a major foreign policy attack on Republican Donald Trump, using a speech in San Diego to cast the Republican as unqualified and dangerous.

Clinton will berate him for being too friendly with North Korea and too harsh on European allies in a foreign policy speech in California designed to portray the billionaire businessman as unfit for the White House.

The speech in San Diego comes as the former secretary of state seeks to shift her attention to the Nov. 8 presidential election against likely rival Trump and away from Bernie Sanders, the US senator from Vermont who is continuing his longshot bid for the Democratic nomination.

Clinton, who has repeatedly called Trump a “loose cannon,” will seek Thursday to contrast her foreign policy experience with Trump’s. Foreign policy adviser Jake Sullivan said Clinton would make clear how high the stakes are in the race, as well as share her “larger vision of who we are, what we’re all about as a country.”

“She is going to make clear why Donald Trump is simply unqualified to be commander in chief,” Sullivan said, adding that the speech “will go into specifics in a very direct and clear way about what makes Donald Trump unfit, both in terms of temperament and ideas. This is as full-throated and full-bodied a case as you will have seen from anyone on the danger that Donald Trump poses.”

Trump has said he would sit down with North Korean leader Kim Jong-un to try to stop Pyongyang’s nuclear program and has criticized the decades-old NATO alliance with mainly European nations as obsolete and too costly for the United States.

During an appearance in Newark, New Jersey Wednesday, Clinton assailed Trump over his past statements, criticizing him for proposing to ban Muslims from entering the country, for advocating the use of torture and for saying other countries should acquire nuclear weapons.

“This is not just divisive rhetoric, my friends, this is dangerous,” Clinton said. “What he has already said has given aid and comfort to terrorists.”

Clinton and Trump offer starkly different visions of US foreign policy. Clinton’s detail-oriented proposals reflect the traditional approach of both major parties.

Despite differences on some issues, such as the Iraq war and Iran, Democratic and Republican presidents have been generally consistent on policies affecting China, Russia, North Korea, nuclear proliferation, trade, alliances and many other issues.

Trump says US foreign policy has failed. His strong-man “America first” approach is short on details, but appeals to the emotions of angry voters who believe that successive leaders have weakened the country, made it vulnerable to terrorism and have been duped into bad trade deals that have cost American jobs.

Trump accused Clinton of lying about his foreign policy plans at a rally at an airport hangar in Sacramento, California, Wednesday night.

“She lies. She made a speech and she’s making another one tomorrow. And they sent me a copy of the speech and it was such lies about my foreign policy,” Trump said.

“They said I want Japan ... to get nuclear weapons. Give me a break,” he objected. “I want Japan and Germany and Saudi Arabia and South Korea and many of the NATO nations — they owe us tremendous. We’re taking care of all these people. And what I want them to do is pay up.”

Trump has suggested in the past that he might be OK with Japan one day obtaining nuclear weapons.

Clinton’s campaign hopes her foreign policy experience will appeal to voters who may be wary of Trump’s bombastic style and lack of international experience. They hope those points, combined with Trump’s controversial statements about women and minorities, will give Clinton opportunities with independent and moderate Republican voters.
