Why do you think the author includes these details?whats her purpose?

Malala learns that the most important weapons in fighting this oppressive force are not guns, nor knives, nor bombs. The Pakistani army, using all of these conventional weapons against the Taliban in Swat Valley, is largely ineffective. Instead, the most powerful weapon in fighting Talibanization is speech. Malala's father begins to take on an important role speaking out against the Taliban, and through his example she learns to have the courage to speak out. Words are her weapon, because words can reach a wide international audience and inspire others to do something about the situation. Malala will continue to use words to change the world even after she has left Pakistan—in fact, writing this memoir is one of the ways in which she does so.
