Did anyone expect anything different out of China? Of course not. It's effectively an open secret that China actively seeks out and attempts to surpress the Internet, not just for their own people, but for everyone. They have a history of decades of humans-rights abuses; these are things that you'd have to be foolishly uneducated to think even BEGINS to compare with anything done by Western nations in the past half-century. I'm talking about secret police who kidnap peaceful protesters, where they vanish to secret prisons where they are physically tortured and (usually) never heard from again.
Obviously, China holds that it's in their best interests to make sure that this ugly side of their country, the evil acts that the "People's" Communist Party commit for the sake of keeping their own people from overthrowing them, is kept entirely out of sight and mind. They have shown that they will stop at perhaps nothing in their impossible attempt to keep it covered up. It was well noticed that this more recent hacking attempt was targeted against human rights activists the world over; China is attempting to attack those that stand for human rights.
As for China and the 'National Debt,' contrary to popular belief, the Chinese don't hold a majority of the US Government's debt. Hell, they don't even hold a single trillion dollars. Discounting Hong Kong, Chinese ownership of federal debt has actually
SHRUNK, to, at the last report just a couple months ago, at a mere
$789.6US billion, making it a mere 4.3% above Japan's share. These numbers are from
The US Department of Treasury themselves.
So if the debt's over $10US trillion, and even the top two foreign countries account for less than $1.6US trillion combined, who holds the rest? Government institutions. $4.5US trillion is held as intra-governmental holdings, such as Social Security and the Federal Reserve. That's a whopping 36.6% of all the debt, dwarfing China's 6.4% share.
