You are wrong about China being a friend, even at policy level.
Regardless of their actions, on paper they’re still a “friend” (note the quote marks). Because, on paper i.e. for legal purposes, they’re not designated as an enemy or under some kind of sanctions, he’s not legally a traitor.
I’m not saying that China means only the best for the US. Far from it. I too believe they’re a brutal communist dictatorship that holds far too much influence over the US financial market (among other things). And like Russia, China is not really the US’s friend and certainly means the US harm. But until that knowledge sinks in up in DC, China will continue to be a “friend” at least on paper. And likewise, until that happens, what Prince is doing isn’t actually treason in a legal sense.
Like I said, don’t be sloppy with the language. We’re likely to need it soon, and the last thing we need is for important words like “treason” to have their meanings diluted.
