A recent worldwide threat report delivered to the Senate Select Committee on Intelligence by leaders of the Intelligence Community made clear that China is the largest national security threat to the United States.  

This week, State secrets talks to one of the world's most renowned experts on the U.S.- China relationship, Graham Allison. 

His 2017 book Destined for War: Can American and China Escape Thucydides' Trap? was a national and international best seller.

Allison has just recently returned from China, where he spoke with Chinese officials about the State of Affairs with the U.S. We caught up with him when he was in his office at Harvard University, where he has taught for more than five decades.
