WASHINGTON - Democratic presidential front-runner Hillary Clinton will berate Republican Donald Trump for being too friendly with North Korea and too harsh on European allies on Thursday 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 U.S. senator from Vermont who is continuing his longshot bid for the Democratic nomination.
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.
"It's important that people understand this is not just about Republican versus Democrat, that Trump is unlike any presidential candidate we have seen and he is fundamentally unfit to be our commander in chief," Clinton aide Jake Sullivan said in an interview before the speech.
California, the most populous U.S. state, is among six states that hold Democratic nominating contests on Tuesday.
Clinton already has a nearly insurmountable lead over Sanders in the delegate count, but is hoping a decisive win in California can help her clinch the nomination and quell concerns about divisions in the party before the general election.
Several polls show the race tightening and Clinton is hoping to stave off an embarrassing loss in California, where Sanders has been vigorously campaigning. On Thursday, he planned a rally with actress Susan Sarandon in Modesto, California.
Clinton has already delivered several speeches on foreign policy and national security. Her address in San Diego will not break new policy ground, but will mainly respond to Trump's recent comments, her campaign said.
The former U.S. senator from New York will argue that Trump's statement that he would be willing to talk to Kim Jong Un, made in a Reuters interview in May, has only emboldened the North Korean leader, Sullivan said.
A column this week in DPRK Today, one of North Korea’s state mouthpieces, described Trump as a "wise politician" and Clinton as "thick-headed Hillary."
"Donald Trump’s statements about North Korea show that he has more interest in making Kim Jong Un like him than backing up our friends and allies in the region," Sullivan said, noting that South Korea has worked with the United States on missile defense.
Trump's remarks on the decades-old NATO alliance of 28 nations will also elicit a response from Clinton, Sullivan said. The New York businessman has said member nations should pay for their own defense to ease the U.S. financial burden and that the alliance itself needs reconfiguring.
Sullivan, who worked with Clinton at the U.S. State Department, said burden-sharing is "not a novel point" within NATO and that Clinton will highlight her record of getting allies to “step up” and share defense costs.
Clinton, however, would not walk away from the alliance, which coordinates with the United States on counterterrorism, nuclear proliferation and other issues, Sullivan said.
Other states holding nominating contests on June 7 are Montana, New Jersey, New Mexico, North Dakota and South Dakota.
California Governor Jerry Brown this week endorsed Clinton in the Democratic contest, saying she was the “only path forward” to “stop the dangerous candidacy of Donald Trump.”
