China would not be impressed. They would no longer exist if they attack us. The F-22s are in the process of being fielded. The JSF is coming soon. Just one nuclear submarine carries more nukes than China's entire arsenal combined. They are no match for us.
They have over 300 nukes, well enough to reach most of our western half of the country, up to Salt Lake City. The loss of California, Seatle and Portland would end our economy. Also, thanks to Clinton, they have MERV warheads.
