When you have an anti-press president who would prefer that he could lead in a totalitarian manner, the result is a president who never admonishes foreign governments for taking out targets. He wasn't upset about the spy poisoning in the UK and he wasn't upset about the Saudi King going after a guy. He would not get involved in these things if the press didn't question him about it.
Why did anyone have the chance to care about the UK poisoning? Because the UK and other European nations made a big deal of it. They elevated it so the world could talk about it.
Why did anyone get a chance to care about the Kashoggi think? Because Turkey was thrilled to have a chance to rat out Saudi Arabia on something, so they cried bloody murder.
I think the world is outraged by all of it so long as somebody cries afoul loudly enough that they hear about it. The UK poisoning thing and years of articles about violence against opposition candidates in Russia demonstrates that the world does care and that those things do make it into the news. Maybe you've become desensitized to it?
Or maybe you just think nobody cares because your president doesn't care.
