How is this a debate? Anthropic's AI was used in military/defense operations. When Anthropic discovered this and disclosed it publicly, they attempted to revoke access and went after the government demanding it not get used in such a way. This would be a supply chain risk to any government.

If Lockheed Martin disabled weapons systems when it discovered the Air Force using its fighters over Iranian airspace based on Lockheed's ideological views, I'm pretty sure they would be labeled a supply chain risk at minimum. What is the issue here?

The government canceling that specific contract with Anthropic is fine. It is too vast a scope to deny Anthropic to work with any other companies who also happen to be defense contractors. Lockheed Martin for example cannot be sure now if it won't be sued if some employee uses Anthropic for help with accounting or anything unrelated to defense.
