Yes, obviously- but one of our closest allies shorting us on steel supplies in a time of crisis has never happened, while espionage from China-produced tech is happening right now. Which should be our priority?

Though it is, because it happened with Kobe Steel. (Not saying Canada specifically.)

They faked the data on what it could handle; and with things such as aircraft, lives depend on that data.

That isn't a Japanese steel concern though, that's a steel manufacturing concern. U.S. Steel could do the same thing.

But they are saying that Canada would cut us off from their steel production in a time of need, which is a pretty absurd assessment of the situation.
