Elon Musk has formally challenged Russian President Vladimir Putin to “single combat.” If the Tesla CEO wine, Putin has to leave Ukraine.

The Tesla chief executive tweeted: “I hereby challenge (Vladimir Putin) to single combat.

Of course, the Kremlin was tagged in the photo, which also included Putin’s name in Russian and Ukraine written in Ukrainian.

“Do you agree to this fight?” Musk demanded to know in Russian.

Elon’s challenge is just one of several posts he has shared about the conflict in Ukraine.

On March 5, a video was posted showing Musk speaking to Ukrainian President Volodymyr Zelensky.

The same day, he tweeted: “Hold strong Ukraine.”

The always fair Musk added: “And also my sympathies to the great people of Russia, who do not want this.”

Following Russia’s initial move into Ukraine, Mr Musk granted Ukraine access to SpaceX’s satellite-internet system Starlink – a system of around 2,000 satellites designed to bring web access to underserved areas of the world.

Mr Zelensky thanked Mr Musk for that support, tweeting: “I’m grateful to him for supporting Ukraine with words and deeds.”
