Recently, I mentioned in a post that one of the nations that I was particularly concerned about was China because they have been spying on us and have been building up their defensive weapons technology. And at the time someone commented that I was “loony” because China have invested so much money in America that they would never do anything to take us down. But I was right:

A Chinese submarine stalked a U.S. aircraft carrier battle group in the Pacific last month and surfaced within firing range of its torpedoes and missiles before being detected, The Washington Times has learned.
The surprise encounter highlights China’s continuing efforts to prepare for a future conflict with the U.S., despite Pentagon efforts to try to boost relations with Beijing’s communist-ruled military.
Ha! Take that and know that I have reason for saying what I do. I’m not some tin-foil hatter, I’m not just making this stuff up.

According to the defense officials, the Chinese Song-class diesel-powered attack submarine shadowed the Kitty Hawk undetected and surfaced within five miles of the carrier Oct. 26.
The surfaced submarine was spotted by a routine surveillance flight by one of the carrier group’s planes. The Kitty Hawk battle group includes an attack submarine and anti-submarine helicopters that are charged with protecting the warships from submarine attack.
According to the officials, the submarine is equipped with Russian-made wake-homing torpedoes and anti-ship cruise missiles.
The Kitty Hawk and several other warships were deployed in ocean waters near Okinawa at the time, as part of a routine fall deployment program. The officials said Chinese submarines rarely have operated in deep water far from Chinese shores or shadowed U.S. vessels

However, critics of the program in the Pentagon say China has not reciprocated and continues to deny U.S. military visitors access to key facilities, including a Beijing command center. In contrast, Chinese military visitors have been invited to military exercises and sensitive U.S. facilities.
Additionally, military intelligence officials said Adm. Fallon has restricted U.S. intelligence-gathering activities against China, fearing that disclosure of the activities would upset relations with Beijing.

“Given the long range of new Chinese sub-launched anti-ship missiles and those purchased from Russia, this incident is very serious,” he said. “It will likely happen again, only because Chinese submarine captains of 40 to 50 new modern submarines entering their navy will want to test their mettle against the 7th Fleet.”
Pentagon intelligence officials say China’s military buildup in recent years has produced large numbers of submarines and surface ships, seeking to control larger portions of international waters in Asia, a move U.S. officials fear could restrict the flow of oil from the Middle East to Asia in the future.

Not to mention keeping us away from Asia.
See, I’m not a tin-foil hatter! I’m someone who’s informed and knows that you can’t trust communist countries. They don’t think the same way we do, their goals and our goals are completely different.
