Consider this, if by the 2020 every food resource in the world is needed to feed just China's population...?

...and if America is the breadbasket of the world, one can be sure that they are at least planning possible invasion scenarios, even if not serious ones. A friend of mine commented that not China alone but a consolidated Asian force could be successful especially, if as I believe, that they could compromise alliances of Mexico and Russia with the US. They could attack with millions from the south, from the north (through Alaska and Canada) from the sea and air. Any thoughts??
