@Jura , why are you posting the same (or very similar) articles about those 2 Canadians being arrested again and again? We get it: those 2 Canadians were arrested.
Detaining 2 measly Canadians is not enough. To shellshock Canada back to its sense, probably need to arrest far more Canadians and with strong possibility of death sentences.
Let's not get too wild here. The goal here is to scare the Canadians into seeing that truly siding with the US is dangerous. Now I said, "truly," but openly, they must side with the US. No matter how much China boycotts them or arrests their citizens, the final fact is that the US buys 75% of their exports. They must keep the US happy by openly siding with the US; you cannot change that. BUT China can inflict enough pain and fear into them that they "truly" become neutral.
I think China should hold the 2 Canadians and whatever happens with Meng's case, mirror it. If they extradite her and she's sentenced, give these 2 the same sentence.
For example, when the US asks Canada to arrest a Chinese citizen, Canada must say yes or suffer America's wrath. That's open. If they are truly on America's side, they will do it. If they are truly neutral and don't want to anger China, they can pretend that person never came to Canada. If the US already knows they are coming and made the request beforehand, then the Canadians can secretly tip the Chinese to change that person's flight plans to avoid Canada, and any other country that might do America's dirty work. That way the US isn't offended when that person happens to not go to Canada, and won't inflict harm to Canada's economy. That should be the goal. You cannot get Canada to openly tell the US to go to hell because in North America, the US has too much economic clot... for now.
What we're doing now is that, plus punishing the Canadians. For all purposes, I think the Canadians already get the message, but the punishment to satisfy Chinese anger has not fully run its course yet. If you start killing people... well now that takes things into a whole new realm. The Canadians will have a lasting hatred of China and will wholeheartedly side with the US. We don't need that; the US needs that. So punish them, scare them, but don't give them a mental scar they'll hate you for forever. That way, they can learn their lesson so we can move forward a few months down the road.
