Plan B from Outer Space

What's Plan B if China starts dumping US debt? I'll let Reuters explain:

"The U.S. government should have and maybe still could call on the people of the U.S. to invest in U.S. debt," said David Walker, a former U.S. comptroller general who heads an advocacy group calling on the government to curb the U.S. budget deficit and borrowings.

Did Americans just lose a trillion dollars on houses Washington told us it was just hunky-dory to borrow money to buy? This one's a non-starter.
