The US is broke. It's govt basically has no spare cash. It has to either raise taxes on the rich (which it cannot do with the current Congress) or it has to drastically reduce its discretionary spending. It cannot continue to borrow from China indefinitely. Repeat - the US is broke, It cannot afford another war even to please its Zionist masters.
