Well - they should go for it. The US has a lot of good athletes and many people with a pioneers attitude - I think it's only a question of time that 'soccer' becomes an even more popular thing at your place - it's nothing less then the worlds most wanted trophy.
...and I think it's overdue that the chineese and indians come up with a decent football team - can't even remember them having ever qualified.
Chinese qualified under Bora Multinovic in 2002; they were in the same group as Brazil, Costa Rica, and Turkey.
