So the Chinese military was smart enough to do serious cyber-espionage but so stupid they didn’t cover their tracks? I call bullshit on this.
The FBI tracked the computer attacks to Unit 61398 of the Third Department of the People’s Liberation Army, headquartered in a building in Shanghai, officials said.
We are supposed to believe all the attacks came out of one building and the Chinese were too dumb to disguise their location. This does not compute and seems  a propaganda attempt by the US, especially since there’s no chance the five hackers in China will ever face trial here.
