From the ignored alert to the war in Afghanistan: 11 facts about the attack on the Twin Towers

I cannot write a detailed summary because the full content of the article with the 11 facts was not included in your message. I only have the title and a brief introductory description, which indicate that the article is authored by Nuno Rogeiro and addresses facts about the attack on the Twin Towers, from the warning signs that preceded the attacks to the subsequent consequences, including the war in Afghanistan. If you provide me with the full text of the article, I will then be able to write a complete and detailed summary based on the information available.
