Wal-Mart is a huge part of the reason China is not the threat it could be.
China's economy is dependant upon our own. Indeed, all it's savings are in U.S. Treasuries.
A serious attack on us would not only cripple their economy, it would piss away all they have saved.
The billions the Chicoms have invested in upgrading their military had to have come, in large part, from W-M dollars. Their economy does depend upon us, but the enormous trade imbalance in their favor cannot be helping our economy.
