Honestly I hope you are right, but I dont see it in my every day life.
The majority of the people I meet and see in public dont supply much evidence to support that conclusion.
In the bars I see the CNN or Fox on one TV with the sound off, on another a ball game or a sitcom with the sound on.
If you ask people they know a little about what is going on, but no depth to their knowledge.
IMHO Americans generally are people of intellectual laziness. And I havent seen much to change my mind since 9/11. Once the fighting war is over they will quickly loose interest until the next big terrorist attack.
