After having killed Al Qaeda leader Ayman al-Zawahiri with a drone that hit the home he had been hiding in Kabul, the United States has, to a large extent, finished avenging the 9/11 attacks.
The perpetrators were killed in bloody attacks, and Osama bin Laden was then killed by Navy SEALs in May 2011 in Pakistan. Khaled Sheikh Mohammed, the “mastermind” behind the attacks, remains in Guantanamo Bay after being arrested in Pakistan years ago. Many of the other perpetrators are either rotting there with him or were killed by the US.
