During the last few decades, many nations have felt the wrath of a terrorist organization in many different ways. Many of these attacks can be traced back to a multi-national terrorist group called Al-Qa"ida. Al-Qa"ida has been supporting Muslim extremists around the globe including areas such as Afghanistan, Bosnia, Chechnya, Tajikistan, Somalia, Yemen, and Kosovo. They also have many training camps set up around the globe. The goal of Al-Qa"ida is to unite all Muslims under one government that follows the ways of Caliphs. Osama Bin Laden is a key member of this terrorist organization. He has stated that the only way to unite all Muslims under one government is to use force. With this statement, he has been a key financial supporter and planner of terrorist attacks around the globe. Osama has been number one on the most wanted list for many years, but has not been caught. The United States went after him after the events that occurred on September 11th, 2001, but had no luck with locating him. On this date, four flights were hijacked within the United States and two were flown into the World Trade Centers, one was flown into the Pentagon, and the last one crashed in Pittsburg. Some other terrorist attacks just from 2002 that have been linked to Osama and Al-Qa"ida include a bombing of a hotel in Mombasa, Kenya, a nightclub bombing in Bali, Indonesia, a suicide attack on the MV Limburg off the coast of Yemen, and a firebombing of a synagogue in Tunisia. These are just a few of many events that have occurred. Terrorism is used because it is cheap and very effective. All nations are afraid of a terrorist attack happening within their borders so it creates fear, even before something has happened. Al-Qa"ida will pay the family of a suicide bomber anywhere from one-thousand to fifty-thousand dollars to have the person commit the act of terrorism. Most nations have taken action in the way of stricter border controls.
