Last week, Musk challenged Putin to a fight for the fate of Ukraine, and now he wants the Russian president to be stopped.

Musk said that we cannot let Putin take over Ukraine.

During an interview with the CEO of Insider, Musk talked about the new Gigafactory in Berlin, which opened on Tuesday. He talked about the invasion of Ukraine by Russia.

More than 10 million Ukrainians have been displaced by the Russian invasion. According to the UN Refugee Agency, more than 3 million Ukrainians have fled to other countries.

Musk said it was surprising to see such a war in this day and age.

He said that he thought we had moved beyond such things. If you can get away with it, then this will be a message to other countries that they can too.

Musk talked about the US government's response to the invasion.

He said that the American government has done more than people realize. It is important to do something serious.

President Biden last week announced another $800 million in military aid for Ukraine, bringing the total US security assistance committed to the country to $1 billion in a week. He said the package includes the most cutting-edge systems, including 20 million rounds of ammunition, 800 anti-aircraft systems, 9,000 anti-armor systems, and 7,000 small arms like machine guns, grenade launchers, pistols, and shotguns.

The US and NATO would respond if Putin used chemical weapons in Ukraine, Biden warned Russia on Thursday.

The US has accused Russia of committing indiscriminate attacks on civilians. The United States believes that Russia's forces are committing war crimes in Ukraine, according to a statement by the Secretary of State.

Biden called the Russian president a war criminal.
