The founder and CEO of the company doesn't seem to be bothered by the threat from the Russian space chief.

On Sunday, Musk posted a note to his followers that he said was from the head of Russia's federal space agency. The note claimed that the equipment for the Starlink system had been delivered by the U.S. military to the Nazi Azov battalion.

According to an English translation posted by Musk, he is involved in supplying the fascist forces in Ukraine with military communication equipment. You will be held accountable like an adult, no matter how much you play the fool.

The Starlink satellite internet service is active in Ukranian with more terminals on the way.

Musk acknowledged on Sunday that this sounds like a threat.

It has been nice knowing if I die under mysterious circumstances.

Musk's mom, Maye, didn't like that glib response, and she also had two angry-face emojis. The billionaire replied "Sorry!" I will do my best to live.

It doesn't seem like Musk is concerned about his safety, which is unsurprising given that he is prone to hyperbole. If sanctions aren't lifted, Russia may leave the International Space Station program, but it continues to be more or less business as usual.

The two men have traded barbs before. The United States should use a trampoline to get its astronauts to the International Space Station, as a reference to the fact that the nation was completely dependent on Russian Soyuz for crewed orbital missions. The deputy prime minister of Russia at the time, Rogozin, was angry about the sanctions imposed after the nation invaded and annexed the peninsula.

In May 2020, the reliance was ended by the launch of two NASA astronauts to the International Space Station. After the liftoff, Musk said that the trampoline was working.

The United States Agency for International Development has been open about sending Starlink terminals to Ukraine to help it maintain its communications infrastructure during the ongoing invasion by Russia. After the invasion began, Ukrainian officials asked for equipment.
