No country can successfully sell their exports into every country in the world in every industry. Successful economies (like the Germans) identify certain industries as "national champions" and the governments supports and helps those industries to try to obtain a technologically advanced and globally dominant position.
What are the US national champion industries that the USA should have a national policy of supporting? Which US industries can still hope to dominate on a global basis and export US products?
Here's my list of successes and potential successes:
Telecom (Juniper, Cisco)
Offshore Oil Drilling (Oceaneering, Cameron, Diamond, Atwater etc.)
Passenger Airplanes (Boeing)
Defense (General Dynamics, etc.)
Internet (Google, Facebook)
Computers, electronics (Microsoft, Apple)
Software and Business software (MS and various)
Electric cars (Fiskar)
GPS and other Space-related industries (Trimble, Garmin, Orbital Sciences)
Oil production and exploration technology and shale gas fracking

FAILURES:
I think the US car industry to going to shrink and maybe die.
The US steel industry is essentially dead
US shipmaking is dead (except for the military)
US trainmaking is dead
The US screwed up by not promoting nuclear power as a national industry.
The Obama administration may kill off the Offshore Oil Drilling industry if they don't start letting it operate again
The oil majors are going to die unless they can migrate into natural gas majors or biofuel majors or something like that
