After 23 years, we still need to remember the lessons of 9/11

It’s been 23 years since America watched in horror as the Twin Towers fell on live TV.

Nineteen al-Qaeda terrorists, hailing from Saudi Arabia, the United Arab Emirates, Egypt and Lebanon, hijacked four planes and killed 2,977 of us, shaking the nation to its core.

America was suddenly, brutally awoken to the menace of those who hate our country and what we stand for.

Heroes stood up: Todd Beamer and his fellows on Flight 93; firefighter Stephen Siller and his Brooklyn-Battery Tunnel run; Morgan Stanley’s visionary Rick Rescorla and so very many more . . . some whose names we’ll never know.
