There were several factors that contributed to bin Laden's decision to target the World Trade Center, including:
1. U.S. support for Israel: Bin Laden believed that the United States was supporting Israel in its conflict with the Palestinians, and he viewed this as an attack on Islam.
2. U.S. military presence in the Middle East: Bin Laden was also opposed to the presence of U.S. military forces in the Middle East, which he saw as an infringement on Muslim territory.
3. U.S. sanctions against Iraq: Bin Laden was critical of U.S. sanctions against Iraq, which he believed were harming ordinary Iraqi civilians.
4. Bin Laden's personal beliefs: Bin Laden was also driven by his own religious beliefs to carry out the attacks. He believed that it was his duty as a Muslim to fight against those who he perceived as enemies of Islam.
The attacks on the World Trade Center were a major turning point in the history of the United States and the world. They led to the U.S.-led War on Terror, which has had a profound impact on global politics and security.
