“Just left Ukraine. What I saw proved to me we can’t give up on the Ukrainian people. Everyone wants this war to end, but any agreement has to protect Ukraine’s security and can’t be a giveaway to Putin. Let me tell you about my trip and why it’s important we stand with Ukraine.” - Mark Kelly

Musk replied directly to that post: “You are a traitor.”

Kelly fired back the next day: “Traitor? Elon, if you don’t understand that defending freedom is a basic tenet of what makes America great and keeps us safe, maybe you should leave it to those of us who do.”

Musk later doubled down in media appearances, stating that putting “the interests of another country above America” makes someone a traitor.

I don't see Musk making those statement about US helping the interest of other countries.

It seems like stopping Russia from being an aggressor is in the direct interest of the US. Why would Musk think otherwise?
