It os proven that Japaneese; finnish, and dutch high shoolers are smarter than american collegdebstudents, and oud nationalneducation in the devolped is around the secind worst.

Only less than the countries who have less religion than them. It's been show that religion totally fails it promises http://www.skeptic.com/reading_room/religious-belief-and-societal-health/. It also does harm, ex: trying to teach religious belief (creationism) instead of science.
The smartest Americans are actually smarter than the smartest from other countries.
Wisdom isn't determined by nationality
There's no evidence that intelligence is related to nationality/race, furthermore, America still has an incredibly high amount of new inventions yearly.
The average IQ of Americans in 2010 was 98, above most other countries and far more than the country with lowest IQ at the time: Venezuela, with an average IQ of 83. Of course, IQ tests aren't the only nor the most reliable method of discovering intelligence, but it is still reliable enough and the most familiar method.
No, you can look up average IQ by country, they aren't the highest but they aren't the worst, with white people gradually becoming a smaller percentage of the population, the IQ will drop, though.
Obviously not. Americans aren't the smartest but they are far from the dumbest.
I doubt very much they're the smartest, but I find it unlikely they'd rank below countries where most children don't get to go to school.
America is statistically around 17th place out of over 200 countries. If the question was about wisdom (common sense) rather than intelligence, then the answer would definitely be yes.
Intelligence and knowledge are very different things. Knowledge is usually acquired through study and/or experience. Intelligence is your ability/capacity to learn, knowledge, and to apply it. I don't think country of origin has anything to do with intelligence, more like genetic lottery. If you meant knowledge, we aren't the worst, but certainly far from the best.
more ignorant though
