Republican presidential Donald Trump asserted on Sunday that Democratic hopeful Hillary Clinton had killed "hundreds of thousands of people with her stupidity."

During a Fox News interview that aired on Sunday, Trump told Chris Wallace that he would beat Clinton in a general election.

"She's got no strength, she got no stamina. Everything she does is like theatrical," Trump said as he waved his arms to mock Clinton. "She's the one that caused all this problem with her stupid policies. You look at what she did with Libya, what she did with Syria, look at Egypt."

"She was truly -- if not 'the' -- one of the worst secretary of states in this history of the country," he added. "She talks about me being dangerous, she's killed hundreds of thousands of people with her stupidity."

Wallace, however, seemed skeptical about that claim: "What do you mean she's killed hundreds of thousands?"

Trump argued that the "Middle East is a total disaster" because of Clinton and President Barack Obama.

"She traveled back and forth, but look at all problems," he opined. "Look at as an example, Iraq, total disaster. They didn't get us in but they got us out badly."

"Look at Libya, look at Benghazi. Our ambassador, he wired her five or six hundred times asking for help," the GOP hopeful insisted. "She'll take her friend's call every time."

"Hillary Clinton doesn't have the judgement, she doesn't have the strength or the stamina," Trump concluded. "She will be a terrible president -- and I think I'll win."
