absolute rubbish as long US remaing the hub of innovation and the largest industrial base all the problems can be sorted out and the fact that any nation is more than willing to lend to USA due to assurity of their mighty industrial base. Only possibily of US going down in near future is a massive natural calamity like hurrican or earth quake which destroys industrial base on a wide scale upto an irrecoverable level.
When I can see a made in China / Russia / India / Taiwan equivalent for my Intel processor and a Russian T50 taking it on F-35 and a Chinese made nuclear aircraft carrier will be the day I would be a beliver of serious competiton to USA. Until then sit back relax and enjoy this "White House" entertainment!
