In any meaningful sense America has already forgotten. Little or nothing about that day is taught in our Leftist schools. TV networks will not replay the horrors of that day, claiming it is too sensitive, such as the footage of people jumping to their deaths to avoid burning alive. Iran's funding of Islamic terrorism, despite the fact that most of the suicide terrorists of that day were from Saudi Arabia, did not deter Obama from sending billions in cash to Iran, nor Biden from trying desperately to treat Iran as a responsible nation that can be reasoned with. Most "letters to the Editor" today that talk about Islamic radicalism and the danger of these people to our nation will never be printed and will be considered unacceptable "Islamaphobia". And I would be willing to bet that today's "woke" military spends more time indoctrinating our troops about the dangers of "White extremists" than it does about radical Muslims and what those people did on 9/11. To people of 25 or younger, 9/11 is as much ancient history, and thus meaningless to them, as is Pearl Harbor today. The national unity that we felt after 9/11 lasted for less time than ever could have been imagined on that date.
