There's ONE country with the disposable income to do that, and that country is the US of A.
China is Enron with a small nuclear arsenal. By the time they get a moderate-sized one together, they'll be shooting 'em at each other instead of us.
With 1.) foreign investors pulling out of the USA, 2.) new tax laws discouraging foreign investment, 3.)future terrorist attacks damaging the economy, 4.) America's vanishing manufacturing industry, and 5.) China's growing economy... (former US manufacturing jobs and investment going to China) How before they equal, or surpass us?
China doesn't care about now...They care about tomorrow. Every thing I see, read, hear clearly states that the people in charge have no idea what tomorrow brings.
