After Osama bin Laden, leader of the Islamic militant group al-Qaeda, took responsibility for the 9/11 attacks, President George W. Bush launched a battle against violent extremist organizations that threatened the security of America. His fight against terrorism sent millions of U.S. troops into battle in Afghanistan and Iraq. This book looks at how President Bush led the War on Terror, the challenges and success of these efforts, and how his actions have shaped the world we live in today. Sidebars and quotes highlight key events, while full-color photographs and straightforward, yet compelling text bring this very recent war to life for readers.
