Daniel Pearl was killed by terrorists, against whom the US was already at war. Kashoggi was in Istanbul working for an American news organization. No, it would not be right to go to war over that. But sanctions of some sort have been imposed on Russia for poisoning a defector and his daughter in England. Sanctions can be imposed on the KSA for murdering a journalist in Instanbul.
Has Iran returned our retired FBI guy they abducted off that island yet? The former FBI guy who was looking into Hezbollah cigarette smuggling and who just happened to run into a black American-born guy right before his disappearance, a guy who had been working for years as a “journalism exec” for Iran TV?
You know it all comes down to helping Iran, particularly when Isikoff and Klaidman are involved in pushing the Khashoggi story.
