I challenge Putin to single combat and the stakes are Ukraine, Musk said in a Monday morning post.

In a follow-up message in Russian, Musk asked if the Kremlin would agree to the fight.

The director general of Russia's space program replied to Musk with a verse from Alexander Pushkin's The Tale of the Priest and of His Workman Balda.

"You are weak to compete with me, it would only be a waste of time," he said. Take my brother first.

When asked if he would be surprised if Putin accepted the challenge, Musk insisted it would be an honor.

If Putin could humiliate the west, then he would accept the challenge, according to Musk.

Surprising Fact:

Mykhailo Fedorov,Ukraine's vice prime minister and head of digital transformation, said that he was sure that Putin could be sent to Jupiter.

Key Background:

This is not the first time that Musk has commented on the war between Russia and Ukraine. In response to Russia cutting the United States off from its rockets, Musk joked that his rockets will be carried by American broomsticks. In late February, the founder of the two companies agreed to give Starlink satellite internet dishes to the people of Ukraine for free and allow them to stay connected despite the fighting.

Forbes calculated how much Musk is worth. He is the richest person in the world with a net worth of $219.1 billion, nearly $50 billion more than the second richest person, Amazon CEO Jeff Bezos.
