U.S. didn’t learn lesson from 9/11

TORONTO — Years after 9/11 and the ‘‘crazy zeitgeist’’ that permeated the United States, Americans have still not learned to know their enemies instead of just hating them, said American political journalist Chris Matthews on Sunday.

In a speech to political science students at the University of Toronto, the host of the CNBC current affairs show Hardball had plenty of harsh words for U.S. President George W. Bush, as well as the political climate that has characterized his country for the last few years.

‘‘The period between 9/11 and (invading) Iraq was not a good time for America, there wasn’t a robust discussion of what we were doing,’’ Matthews said.

He said Bush squandered an opportunity to unite the world against terrorism and instead made decisions that built up worldwide animosity for his administration.
