Jon Lieber, head of Eurasia Group's coverage of political and policy developments in Washington, shares his perspective on US politics:

What is President Biden hoping to achieve by visiting Saudi Arabia?

This week the White House announced that President Joe Biden would make a visit to the Middle East. The most important part of the trip will be a stop in Saudi Arabia and a visit with Saudi Crown Prince Mohammed bin Salman. The President came into office saying he wanted to make the Saudis pariahs for their history of human rights abuses, including the kingdom's involvement in the 9/11 attacks, the murder of journalist Jamal Khashoggi, and an ongoing war in Yemen that has resulted in tens of thousands of civilian casualties. But unfortunately for President Biden, his Middle East strategy has followed the Mike Tyson maxim that everyone has a plan until they're punched in the mouth.
