When Janet Reno blocked the FBI from investigating the Chinese spy on the basis that to investigate a suspected Chinese spy was racism, China doesn't need aircraft.
China got their nuclear secrets; the case will be blown in the courts. In a similar fashion, another Chinese spy was allowed to cop a plea in exchange for dropping further investigation.
Can you imagine plea bargaining on an espionage charge???
Now, watch the Chinese immigration INCREASE into the U.S..
China doesn't need spy aircraft & satellites.
