PROBLEM: As U.S. Secretary of State Rex Tillerson visits the Middle East this weekend  he'll hope to achieve something that has eluded top American diplomats for a generation: sealing a new alliance between Saudi Arabia and Iraq that would shut the doors of the Arab world to neighboring Iran.
The effort to wean Iraq from Iran and bond it to Saudi Arabia isn't new  but U.S. officials are optimistically pointing to a surer footing they believe they've seen in recent months. They're hoping to push the improved relations into a more advanced phase Sunday when  Tillerson  participates in the inaugural meeting of the Saudi Arabia-Iraq Coordination Committee in Riyadh.
 Tillerson  will seek Saudi financial generosity and political support for Iraq  its embattled northern neighbor. Two U.S. officials said  Tillerson  hopes the oil-rich Saudis will contribute to the massive reconstruction projects needed to restore pre-IS life in Iraqi cities such as Mosul and lend their backing to Iraqi Prime Minister Haider al-Abadi. He is treading delicately among a host of powerful countries on Iraq's borders which are increasingly trying to shape the future of the ethnically and religiously divided nation.
 Tillerson 's decision to skip that gathering was widely criticized at the time as a sign of disengagement with his employees  but the official said  Tillerson  adjusted plans to speak by secure telephone to Saudi Foreign Minister Adel al-Jubeir on the Iraq rapprochement.

SOLUTION: Rex Tillerson

PROBLEM: Marco Rubio  sure does.
The idea that Game of Thrones is a deep political allegory (from which  maybe  a certain kind of politician might learn) has been building for years now  but it seems  Rubio  is just now getting the message.
The show is on its seventh season  where the heck have you been? Just last month  the senator  advised Florida residents preparing for Hurricane Irma to "hunker down" and "catch up on Game of Throne — whatever it's called " so you know his binge began recently.
Wonder how  Rubio 's liking it so far. Do you think he's a Podrick Payne or Renly Barratheon  perhaps? How long would  Rubio  survive in Westeros?
Who knows  maybe Game of Thrones could have at least given  Rubio  the skills necessary to win  his  own state in the primary.

SOLUTION: Marco Rubio

Lawmakers did not disclose the specific actions that  Zarif  had discussed as plans for Iranian retaliation.
