North Korea has ramped up its nuclear and ballistic missile programmes in recent months and continually threatened to target the US.
But author Max Boot said Donald Trump must restrain himself or millions of people could die. He told Bloomberg:”I don’t think it’s helpful to anybody to be swaggering about, you know, ‘my nuclear button is bigger than your nuclear button’.
“I mean, this is a very serious issue. If a war breaks out, you have the potential for millions of people to die.”
Mr Boot said North Korea’s nuclear regime will eventually “collapse” but war is not the answer.
He said: “I think what we need to do is to step back from the brink a little bit and not delude ourselves that there is a military solution to the problem with North Korea.
“Ultimately, I think the way we are going to win this conflict is through deterrence and containment.”
Mr Boot compared it to America’s dealings with the Soviet Union. He said: “Sooner or later some day North Korea will collapse.
“In the meantime, we need to avoid starting a war that could be catastrophic and ill-advised.”
North Korea claimed it was a “pipe dream” to think it would ever give up its nuclear programme after the UN imposed brutal sanctions to thwart Kim Jong-un’s regime.
In an effort to stop the rogue nation, the United Nations Security Council imposed tough sanctions on North Korea following its continued missile testing.
The resolution seeks to ban nearly 90 percent of refined petroleum product exports to North Korea.
Following the UN vote, Donald Trump wrote on Twitter: “The United Nations Security Council just voted 15-0 in favour of additional Sanctions on North Korea. The World wants Peace, not Death!”
The North Korea foreign ministry responded to the UN sanctions and branded them an “act of war”.
