you're a noob
EDIT: On monday, some information was revealed, which is in the book
On the Brink: Inside the Race to Stop the Collapse of the Global Financial System ([url]http://www.amazon.com/Brink-Inside-Collapse-Global-Financial/dp/0446561932[/url]). It is revealed in this book that the Russians asked the Chinese government to drop all the USA bonds they owned pushing USA into bankruptcy. However, the Chinese government was co-operative and supportive of USA in the dire times and refused the Russians.
This means either: China will not take over the world with nuclear missiles...

and will be friendly
OR...

Will take over the world by having a renewable energy source while we still rely on fossil fuels, taking over the world through economy
