Staring at the Sun - The Unanswered Questions of 9-11 - Tokyo Journal Magazine

Following September 11, President Bush famously said "If you're not with us, you're against us." If this is the case, Yumi Kikuchi, lecturer, translator, and peace campaigner, is an interesting example of the enemies that America has to fear. Diminutive and smartly dressed, Kikuchi speaks perfect English, worked for an American bank for 4 years, loves American culture, and has dozens of American friends. She is also a relentless campaigner in the Truth and Peace Movement attacking American foreign policy and exposing the anomalies of the 9-11 attacks.

The criticism she refers to is the growing chorus of suspicion and doubt regarding the true events of 9-11 that has spawned a number of alternative explanations. These include Kikuchi's own belief that the American establishment or elements within it were involved in what was, in effect, an attack on their own civilian population. Like most well-adjusted people, however, she initially had great trouble making the leap from faith to entertain such a worrying idea.
