“For example, the first thing many people often ask is: ‘What weapon should I use in my operation?’ But the answer to this question – and it’s an important question – is not as difficult as it may seem. The Mujahid Brother Nidal Hasan used firearms in his assault on Fort Hood, but the fact is, today’s Mujahid is no longer limited to bullets and bombs when it comes to his choice of a weapon. As the blessed operations of September 11th showed, a little imagination and planning and a minimal budget can turn almost anything into a deadly, effective and convenient weapon which can take the enemy by surprise and deprive him of sleep for years on end.”
