I'm just well read. I can also compare the differences in life in the US a few decades ago to what it is now. Few of the adverse differences are caused by terroism or even the "threat of terroism". (Americans are not supposed to cower when threatened.)
...it's no wonder you don't recognize the threat of terrorism.
As I stated previously, I can compare America over a few decades. The decay did not start with 911. It started on Capital Hill, in State governments, and in neighborhoods. It is a creeping crud of the left; and, this is far more destructive than terrorism has been and ever will be. Terrorism will not terminate the US. Crappy politics will.
Yes. Life is much better now. MUCH better!
You must be one of those who think the Ozzie and Harriet days of the 50s and 60s were idyllic.
