Problems do not go away by ignoring them. The problems only grow worse. As for Saudi Arabia they have been somewhat of an ally in the region. Kind of like Russia (U.S.S.R.) was our ally in WWI & WWII. Sometimes bad optics have to be ignored for the greater good as they say. Egypt is an ally in the region, as is Israel. But just because they are allies does not mean that all is okay between us. But the rest are even worse. Reality often sucks because it can leave you with options where all of the options suck. Some suck worse and some suck less. So do you chose to go with the options that suck worse, or less?
We’d be best of choosing to stay out of the ME and let those countries sort it out. I cannot accept that Saudi Arabia is a better friend than any of the countries we’ve destabilized.
