The columnist seems to be at pains to avoid an elephant in the room, namely, that U.S. policy (well before Trump) has been so corrupt and wrongheaded that rivals are succeeding marvellously while friendly states are (mostly) left unable to stay that way.   That's not unique to the middle East (sanctions in support of the US-instigated coup in Ukraine have cost mostly smaller EU countries $30B) but the consequences there are most obvious:

-Turkey and Europe are flooded with refugees from the jihadist warfare in Iraq and Syria,
-Iraq, Syria, and Qatar are finding common cause with an ascendant Iran, and
-western-orbit states e.g. Turkey and !Saudi Arabia! are looking to Moscow for sensible, reliable interest-based diplomacy and trade.

And now Trump seems ready to let Israel push him into releasing Iran to pursue nuclear weapons if it so decides.

Only the military industrial complex seems to be benefitting from any of this.
