The United States may not be the global superpower it once was, but American are still considered the "coolest" nationality in a new international poll.

Social networking site Badoo.com asked 30,000 people across 15 countries to name the coolest nationality and also found that the Spanish were considered the coolest Europeans, Brazilians the coolest Latin Americans and Belgians the globe's least cool nationality, Reuters reported.

"America boasts the world's coolest leader, Obama; the coolest rappers, Jay-Z and Snoop Dogg; and the coolest man in technology, Steve Jobs of Apple, the man who even made geeks cool," said Lloyd Price, Badoo's director of marketing.

Brazilians were ranked the second coolest nationality in the Badoo poll and the coolest Latin Americans, ahead of Mexicans and Argentinians. The Spanish, in third place, were voted the coolest Europeans.

The French were voted cooler than the British, and Canadians cooler than the Belgians -- who were the least coolest nationality.
