Joe Biden's convention cues up photos of Donald Trump with Vladimir Putin and Kim Jong-un and accuses the president of having a 'love-fest with dictators'

Former Vice President Joe Biden enlisted diplomats and longtime colleagues at the Demoratic convention Tuesday to rip President Trump as a threat to the nation's security – and made ample use of images of the president meeting dictators and adversaries. 

'Donald Trump inherited a growing economy and a more peaceful world. And like everything else he inherited, he bankrupted it,' Kerry said. He said when Trump goes overseas, 'it isn't a goodwill mission, it's a blooper reel.'

Kerry accused Trump of 'writing love letters to dictators.' The campaign released a scathing video stocked with foreign policy experts – including former U.S. ambassdor to Ukraine Marie Yovanovitch, who Trump forced out and who testified during Trump's impeachment.

The short film flashes shots of Biden with allied leaders from Canada, France, and Japan.

Trump is shown walking side-by-side with North Korean dictator Kim Jong-un during one of their summits. Trump is seen with Chinese President Xi Jinping at a military ceremony.  

'Donald Trump has had a love fest with dictators including China and Russia, said Rose Gottemoeller, the former deputy secretary general of NATO, as images of Trump and Xi appear. 'He hasn't been standing up to them at all.'  

She said Biden understands the importance of strong alliances.   

'Thanks to President Trump, our adversaries are stronger and bolder,' said Tom Countryman, a former assistant secretary of state.

Jack Weinstein, a retired Air Force general, called Trump a 'danger to national security.'

'President Trump has degraded and debased the presidency and our country in the eyes of the world,' said former Sen. Chuck Hagel of Nebraska, who served as secretary of defense under President Obama.

Former Secretary of State Colin Powell cut his own speech where he said Biden 'will be a president we will all be proud to salute.'

He said Biden 'will stand with our friends and stand up to our adversaries, not the other way around.'

Trump throughout his presidency has defended his relationships with world leaders, including adversaries. He has said he is tougher than anyone on Russia and China, and has accused Biden of being weak on Beijing, pointing to a trip Hunter Biden took with his father.

He made overtures to North Korea, including two summit meetings, after earlier threatening to bring 'fire and fury' and ridiculing Kim as 'Rocket Man.' 

The convention followed up with another video on Biden's friendship with the late GOP Sen. John McCain, whose widow Cindy is backing Biden. 

Although Americans tend to rank issues like the economy and health care as their top priorities, the security attack on Trump follows a tumultuous impeachment following the multi-year Russia probe. 

The Senate Intelligence Committee released a 1,000 report Tuesday on Russian election interference that delves into former Trump campaign chair Paul Manafort's relationship with a Russian intelligence officer and other matters.
