So if China not "buying" will have a positive impact on U.S., why does U.S. try to "sell" the bond to China in the first place? That is self-contradictory, isn't it?
And why would not lending out someone's own money hurting oneself? Especially when the borrower threatens not to pay the money back. Isn't that threat advocated by the same people?
Put it straight, the people behind this article is saying "give me your money, otherwise you will be hurt, and you may never see your money again". That is robbery, nothing else. That robbery did work when the robber had a freaking big gun pointing at the banker's head. But today, the banker has get a big gun of his own, things will change from now on. In the not so far future, with a freaking big gun in hand, the banker will demand or get his past money back, one way or another, in the form of cash, gold, oil or whatever. Treasury bonds are IOUs. IOU is not something one can easily get rid of by scrapping the contract or devalue the denomination currency. IOU is YOM (you owe me) on the banker's side, it is a belief in the mind of the banker that somebody owes the banker. One can say I don't owe you anything any more, but one has to convince the other, that won't be easy.
