BBC2, today, 9pm

This hard-hitting two-part documentary looks at their reasons for being there, beginning with attempts to bring Osama Bin Laden to justice. However, as we’ll get to see, it turned into something else; US soldiers became embroiled in a conflict that resulted in tens of thousands of deaths, and that four presidents desperately tried to end.
