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

What are the lasting implications of Nancy Pelosi's visit to Taiwan?

House Speaker this week, Nancy Pelosi, became the highest ranking US government official to visit the island of Taiwan since the 1990s, setting off an enormous controversy within mainland China that prompted them to fire missiles into Taiwanese waters and directly threaten the United States.

The Biden administration reportedly was concerned about the trip, but nonetheless provided Pelosi with the logistical support that the House Speaker asked for in order to get there.

Pelosi's trip served no obvious purpose other than to show the island the extremely strong level of support for them in Congress, so strong, in fact, that several senior members of Congress are considering a new Taiwan Policy Act that would upend the status quo in US-Taiwan relations and potentially lead to even more blowback from China.
