Comedian Dana Carvey debuted his "warmonger" impression of incoming national security adviser John Bolton on Wednesday night's edition of CBS's "The Late Show" with Stephen Colbert.

The "special guest," who bore the former United Nations ambassador's trademark white mustache, denied reports of being an "unstable warmonger." The skit is a response to critics who fear Bolton will swing Trump's foreign policy toward the right.

“It’s very important to me that nobody thinks President TrumpDonald John TrumpFacebook releases audit on conservative bias claims Harry Reid: 'Decriminalizing border crossings is not something that should be at the top of the list' Recessions happen when presidents overlook key problems MORE has handed the keys to the war machine to some sort of hair-trigger lunatic,” the former "Saturday Night Live" comedian said in the skit. “Because if I heard someone say that, I’d blow them up quick!”

Colbert grilled the faux Bolton on his foreign policy stances, asking whether Americans needed to worry of preemptive strikes against adversarial nations.  

“Stephen, I’m a rational man and reason dictates, whether it’s the ayatollah or some rogue king of Denmark or the person waiting too long in line at the airport tomorrow, you hit them first,” the Bolton impersonator continued.

Bolton, who also served as the undersecretary of State for arms control and international affairs, has suggested the possibility of a preemptive attack on North Korea to eliminate its nuclear arsenal. 

“After talking to you, I can’t believe I’m saying these words: I think you might be more unstable than Donald Trump,” Colbert concluded.

Bolton will officially replace three-star Army general H.R. McMaster as the national security adviser to Trump on April 9.
