Why don't you tell us, or better yet, tell the FBI.
China, it should be remembered, considers us the Main Enemy, the "hegemon", the most serious obstacle to its territorial ambitions, and has repeatedly said war with us is inevitable.
Regarding the bandying about of the label of "bully" by one or two on this thread, consider:
The left made much of the May, 1970 accidental killing of four Kent State students.
By official decree, Chinese troops slaughtered between two and six thousand students demonstrating for democracy in the events commenced on June 4, 1989 in Tiananmen Square and proceeding to violent "Strike Hard" massacres in 140 locations throughout China.
Recall that Bill Clinton claimed George Bush "coddled the butchers of Beijing" in a direct reference to the Tiananmen massacre--yet Bill Clinton sold our missile guidance and nuclear warhead advantage (and much more) to the Chinese, for campaign donations from the likes of PLA Gen Ji Shingde whose boss Gen Xiong Guangkai was in charge of provocations during that operation and who sat with Clinton in talks reestablishing "military-to-military ties" in January 1999 in Washington.
Clinton not only did not accept the offered foreign intelligence help in arresting bin Laden--he so degraded our military readiness that it is common knowledge we were not able to scramble fighter protection in time to protect against the attacks of 911.
Clinton provided China with guided tours of every U.S. military base, installation, facility, exercise, and platform, and systematically degraded U.S. military readiness, training, retention, morale and supply.
One last address of the "bully" charge--where is the first Tootsie Roll, egg roll, sesame roll or baloney sandwich from a compassionate Jiang Zemin to a starving Afghani population? The Chinese feed the muslims what they feed the Tibetans and the Falun Gong: fists, lead, prison camps and death.
Jiang Zemin has much in common with Osama bin Laden in the compassion department. Bully buddies.
Next time: Beijing opens McMethedrines in Burma with 15,000-man Wa Army--to be followed by Burmese PLAN base on Bay of Bengal.
