So maybe Dubya's right after all.

George Washington got spooked by bioterrorism, and look how famous it made him.

From the National Archives:

Before closing a lengthy letter to Congress reporting on a variety of topics, Washington passed along information that he had heard from a sailor: that British Gen. William Howe was sending people out from Boston who had been deliberately infected with smallpox so that they might pass on the disease to the Americans surrounding the city. After seeing an increased number of cases in people coming out of Boston, Washington came to believe that smallpox was indeed “a weapon of Defence they Are useing against us.”
