In trading with China  ...we have aided and abetted the  transfer of a huge industrial  and technology  base  from the west to the east ...folks should  remember that what won the second world war was the Combined industrial  powers of Russia  and  the  US  .... punching out more war machines  than the Germans ...as Mao  said ..."Power  grows from the barrel of a gun "  ....lets hope that when ( not if )  China  begins to exert "Arbitrary measures "  the West will have the industrial infrastructure to respond .
