I honestly didn't like to hear our President call SA a great ally because "jobs" and "economy." He repeated it twice because it was all he could think of to say. This is what happens when you give a clueless businessman the job of President. It sounded pathetic, even if $$$ is at the back of every leader's mind when they make decisions about alliances.
What would you have him do?
An Interpol investigation would be good. But Donald Trump won't allow that because the outcome would embarrass him.
Interpol? What do you think would come of that?
Convictions.
The government of Saudi Arabia, if it is behind this, is not going to turn over it's people.
And if it tries, those people could fight back.
And we would be undermining the current leader, who is probably the best that shitty nation has to offer.
