The former president of Russia has minced no words and issued a stern warning of a nuclear war if the country is punished for Ukraine war crimes.

In the Kremlin's most recent nuclear apocalypse warning, former Russian president Dmitry Medvedev has warned that if Moscow is punished for war crimes, the "existence of mankind" will come to an end.

The close supporter of Vladimir Putin, who is currently the deputy head of the Security Council, stated that the International Criminal Court (ICC) should desist from attempting "illegal" steps against Russia.

The brutal invasion of Ukraine continues to leave a trail of suspected war crimes, including the relentless shelling of civilians, reports of rape and torture, summary executions, and the deployment of prohibited cluster munitions.

Medvedev, who served as Putin's stand-in president from 2008 to 2012, stated Thursday on Telegram, "The notion of punishing the country with the greatest nuclear capability is ludicrous in and of itself. And perhaps threatens the survival of humanity."

He then accuses the United States of attempting to sow chaos and ruin through the ICC, dubbing the Western powerhouse a "daredevil or an imbecile."

The Kremlin source stated all of American history since the conquest of the Native Americans has been a "horrific war of annihilation."

It has become a hallmark of American politics, regardless of who is in power. During World War II, the United States used this method to destroy Hiroshima and Nagasaki in order to justify the enormous costs of the Manhattan Project, the source said.

"Vietnam and Korea, Yugoslavia and Iraq, Cuba, Afghanistan, and Syria are well aware of the tragic results of such invasions - the list is lengthy and is continuously updated," the source added.

Since the end of World War II, the United States has killed more than 20 million people in 37 nations, according to a report published in Global Research.

Medvedev accused the U.S. of attempting to bring Moscow before international tribunals while avoiding accountability for its own wars.

Medvedev added that the number of victims of the criminal policy of the U.S. now is similar to the number of victims of the Nazi dictatorship.

"Who then will give us a show trial? Who are those who murder people and perpetrate war crimes with impunity, but are not truly condemned by the international systems that they finance?" Medvedev said.

Medvedev said this will not work with Russia and that they should know this quite well.
