The main problem is how this ends up affecting the value of the renminby if a lot of them need the help at the same time. That would force a depreciation of the renminby, which they would export as deflationary pressure on the price of Chinese goods on the FSoA market. Good for the FSoA consumer, but terrible for Da Fed, because they would not be able to control the deflation by further lowering interest rates. Right now they're trying to hike interest rates back up.
In other words, the blowback is that it would further destabilize international currency swaps as the BRICS and Renminby compete against the dollar for hegemony over inteernational trade. If the Chinese even come close to winning this baattle, all hell will break loose and I can see no other greater risk for a direct military conflict between the FSoA and the Chinese than this. The FSoA simply cannot allow the Dollar to lose its power as the Reserve Currency for global trade. Tariffs and embargoes of Chinese goods would be instituted, they would be accused of dumping cheap merchandise on the markets and basically driving out of business all their competitors.
This is economic warfare at the highest level and something we need to follow closely. Although most of us believe that even TPTB are not so stupid as to push the button on Gobal Thermonuclear War, a tiger backed into a corner doesn't react using common fucking sense, it lashes out.
Shall we play a game?
