On September 11th, 2001 a horrific tragedy occurred, something that will never be able to be forgotten, something that will forever be remembered in the hearts of the American people. This tragedy affected thousands of people’s lives, a total of 2,996 people were killed and nearly 6,000 were injured, including the passengers aboard all four of the airplanes. This event occurred at the World Trade Center, in New York City. Nineteen terrorists hijacked four different planes, crashing two of them into the Word Trade Center, and one into the Pentagon in Washington D.C. The fourth airplane had an unknown target, but people think that it was the White House in Washington D.C. However, they failed to crash it into the White House because the passengers took over the plane from the hijackers and crashed the plane into a field in Pennsylvania. The terrorist attacks on September 11, 2001 was one of the most frightening moments in United States History; the most important aspects to understand about the attacks are Osama bin Laden, one of the masterminds of the attacks, how the attacks happened, and the effects on United States.Osama Bin Laden Osama bin Laden was born in Riyadh, Saudi Arabia on March 10th, 1957. He was the 17th of 52 children born to Mohammed bin Laden, a Yemeni immigrant who owned the largest construction company in the Saudi kingdom”(history.com staff, 2009). His full name is Osama bin Mohammed bin Awad bin Laden. Osama’s siblings went to school in the West and than went to work for their father’s construction company, but he stayed close to home. He went to school in Jiddah, married at a young age of seventeen and ended having five different wives and 20 children, his wives names were Amal al-Sadah, Siham Sabar, Khairiah Sabar, Khadijah Sharif and Najaf Ghanhem. Like many Saudi men, Osama joined the Islamist Muslim Brotherhood as a young man. “The Muslim Brotherhood is a religious and political group founded by Hassan al-Banna in 1928 on the belief that Islam is not simply a religion, but a way of life. It advises a move away from secularism, and a return to the rules of the Quran as a foundation for healthy families, communities, and states”(Jones and Cullinane, 2013). Osama bin laden became a terrorist around the age of thirty, at that time the Soviet Union was invading Afghanistan, so he joined the Afghan resistance. After it was over Osama bin Laden founded the al-Qaeda network along with Abdullah Azzam in 1988. The al-Qaeda is terrorist group led by Osama bin Laden. He becomes one of the worst terrorist of all time, the things he does will never be able to be forgotten. He has been apart of very many terrible terrorist attacks and caused thousands of lives. Like the Truck Bombing of U.S. Embassies, it killed a little over three hundred and injured nearly five hundred people. Another one is the Bombing of USS Cole, which killed dozens of people, but out of all the terrorist attacks Osama bin Laden has been apart of, the attack of 9/11 was most certainly the worst of them all. The reason this is the worst one is because it killed thousands and thousands of people, and it took done the World Trade Center and the Pentagon in Washington D.C. After the terrorist attack of 9/11 Osama bin Laden was on the FBI’s most wanted list for just over a decade, on May 2nd, 2011 the U.S. Force found where he was hiding, they attacked his base, shot and killed Osama bin Laden and one of his sons. “Afterwards they took his body in a helicopter, and flew him to Afghanistan for official identification, than buried at an undisclosed location in the Arabian Sea less than twenty four hours after his death, in accordance with Islamic practice.”(History.com staff, 2011). Pretty soon after Osama bin Laden was killed, our president Barack Obama announces his death, and says “Justice has been served”. Immediately after hearing this news, crowds of people were cheering out side the White House, everyone was so happy to hear that Osama bin Laden was finally dead.
