Then the poor guy gets attacked not only by fearful foreign governments but also by some on the left:

Gene Sharp, an 80-year-old scholar of strategic nonviolent action and veteran of radical pacifist causes, is under attack by a number of foreign governments that claim that he and his small research institute are key players in a Bush administration plot against them.

Though there is no truth to these charges, several leftist web sites and publications have been repeating such claims as fact. This raises disturbing questions regarding the ability of progressives challenging Bush foreign policy to distinguish between the very real manifestations of U.S. imperialism and conspiratorial fantasies.
...
The office of the Albert Einstein Institution - which supposedly plays such a "central role" in American imperialism -is actually a tiny, cluttered space in the downstairs of Gene Sharp's home, located in a small row house in a working class neighborhood in East Boston. The staff consists of just two employees, Sharp and a young administrator.

Rather than receiving lucrative financial support from the U.S. government or wealthy financiers, the Albert Einstein Institution is almost exclusively funded by individual small donors and foundation grants. It operates on a budget of less than $160,000 annually.

...
Nor have these critics ever presented any evidence that Sharp or the Albert Einstein Institution has ever been requested, encouraged, advised, or received suggestions by any branch of the US government to do or not do any research, analysis, policy studies, or educational activity, much less engage in active subversion of foreign governments. And, given the lack of respect the U.S. government has traditionally had for nonviolence or for the power of popular movements to create change, it is not surprising that these critics haven't found any.

A letter was circulated defending him, signed by H. Zinn, N. Chomsky and 136 others:

We therefore call upon people of conscience to reject the false allegations leveled against Gene Sharp, the Albert Einstein Institute and other groups promoting strategic nonviolent action; to continue to struggle against U.S. imperialism in all of its manifestations; and, to support popular democratic movements engaging in nonviolent action in the cause of human rights and social justice in the United States and throughout the world.

Maybe it's because I'm a Londoner - that I moved to Nice.
