Story highlights Vice President Joe Biden plans to slam Donald Trump's foreign policy proposals

He'll argue bullying is counterproductive and dangerous

(CNN) Vice President Joe Biden denounced Donald Trump's proposed foreign policy on Monday, repudiating the presumptive GOP nominee's embrace of Russian President Vladimir Putin and suggesting his policies on Muslims could foster extremism.

"Our leadership does not spring from some inherent American magic. It never has. We've earned it over and over again through hard work, discipline, good judgment," Biden said during an afternoon address at a foreign policy conference in Washington. The event was focused on setting the national security agenda for the next commander in chief.

Biden's remarks to the Center for a New American Security didn't mention the real estate mogul by name, but the allusions to Trump were plain.

"Our ability to lead by example and draw partners to our side -- that's what has always been America's greatest capability, not empty bluster," Biden said. "Not a sense of entitlement that fundamentally disrespects our partners. Not an attitude, insecurity of a bully. The United States cannot afford to draw back from our responsibilities now. There's simply too much at stake."

Trump's praise of Putin -- he's called the Russian president "a leader, unlike what we have in this country" -- also came under fire in Biden's speech.
