Answer
Brief Explanations:
On September 11, 2001, the terrorist - attacks carried out by al - Qaeda were a complete surprise to the American public. Only the World Trade Center (private - owned but a major symbol) and the Pentagon (a government building) were attacked, not several government buildings. At the time, airline security was not strong. And the attacks were carried out by al - Qaeda against the US, not a case of relations worsening in a two - way sense as the US had already considered al - Qaeda a threat.
Answer:
The attacks were unexpected by the American public.
