I don't trust such sources too much. What I see in my daily biz is that 
most circuits contain tons of American semiconductors, some ST because 
they often have really low prices, and passives are all over the map and 
usually not country-specific.

For jelly-bean parts pricing is everything. Guys like us spec in a 
MMBT3904 and then there are 8-10 manufacturers.

AFAIK the earnings at Infineon are still negative. Not exactly my role 
model for a successfully run semiconductor manufacturer. And, of course, 
one has to ask oneself why other companies such as National earn a 
profit. They must be doing something right.
