What is the most technologically advanced nation?

Opinion: This is shared between China(who doesn't release their technology and the commoners there know little about it), Japan(who happily sells it to America-mostly relating robots, other automatons, and Video Games), and America(who buys it from the other two countries and either expands on it, or invents the basis for it).

1. United States of America

2. Russia

3. China

4. United Kingdom

5. Japan

I think it's:

1 Japan

2 US of America

3 Russia

4 Germany

5 China

6 Israel
