China is still light years away behind the military might of USA, especially in technology. And China knows it. They have to start improving their military fast.
It may take China another 50years to 100 years before their military forces can catch up.
In 50 to 100 years, the world changes. Former enemy-countries become friends. Former friendly-countries become enemies.
Just see what happened in July 2011. US put the Vietnam War memories aside. And sided with Vietnam in the latter's tiff with China over the Spratly Islands.

During the Vietnam War, it was China that supplied logistics, food, ammunition, weapons to Vietnam to fight against the US.
Now in 2011 Vietnam is anti-China.
The biggest monster is not China or North Korea or Vietnam.
The biggest most malevolent monster was, is and will always be Japan. Now Japan is lying low but its ambition is not dead. Their cruelty in WW2 is well documented. Our parents and/or grand parents experienced Japanese cruelty first-hand. So you know what to expect from Japan when it becomes powerful once again.
