( I am reminded of this scenario in Tom Clancey's book 'Debt of Honor' )
In Debt of Honor, a Japanese industrialist initiates an economic war against the U.S. by using a spy to plant malicious code in the Federal Reserve, deleting trading records and crashing Wall Street. This financial attack escalates into military conflict, culminating in a terrorist attack that destroys Congress. Executive Orders picks up immediately with Jack Ryan navigating the aftermath, rebuilding the government, and handling global crises.
