You could argue about the merits of each, but both would have validity:
1) Tell the Saudis to fuck themselves because their leader is a brutal savage.
2) Hold our noses and maintain relations because they are a strategically vital relationship.
The unsupportable, dumbass approach would be to tell them to fuck themselves and then segue to a request for their help in something we think is important.
Pretty sure they don’t teach that in International Relations 101.
