Our Method
Every Decision Tested by Evidence
We begin with the choices available at the time—not simply what later generations wish had happened.
- What problem confronted the president?
- What options were realistically available?
- What advice and information did he receive?
- Why did he choose that course?
- Was the decision constitutional?
- What were its immediate and long-term consequences?
- What might have happened had he chosen differently?
