Saudi Arabia actually issued a statement to the US embassy saying it "condemns ‘malicious leaks and grim rumors". It's funny how nobody openly criticized Saudi Arabia despite all of this, some were just asking for a thorough investigation and that's it. I think at this time there's an audio recording of him being assassinated there.
The most powerful independent government in the world is the EU at the moment, at least in terms of economy, exports and decision making influence (since they can decide that no European countries can do business with a given country). They still sell weapons to Saudi Arabia. Same as the US, Russia, and China (who just openly stated that they want to do MORE business with the Saudis).
Canada is the sole country not doing business with the Saudis, although not by its choice. They were the only ones openly calling out the Saudis for human right violations, and Saudis cut ties, then nobody supported Canada afterward, lol. Canadians were a bit proud and a bit disappointed that nobody supported them when it happened. From the Saudi perspective, Canada has roughly the size of a US state like California, and with the whole world still dealing with them, Saudi Arabia is feeling cocky to the point they feel comfortable just cutting all ties with a single country that criticizes them. The US played it down as two trade partners beefing and the EU withdrew their support of Canada after threats from the Saudis. It's morally fucked up.
