Any US naval ship that tries to intervene in the conflict, we will attack its home port. Any US warplane that tries to intervene in the conflict, we will attack its airbase. Very likely this will include US bases in Ryukyu Islands, Japan, South Korea and Guam.
We'll drop the nukes on New York, Washington DC, Los Angeles, Chicago, Boston, Bay Area...
Just like the Notre Dame cathedral. It's been there for 800 years. Everybody assumes it will be there for a long time still. Then all of a sudden it's destroyed. Washington DC has been there for hundreds of years. Everybody assumes it will be there for a long time still. Then all of a sudden a Dongfeng ICBM attack vaporizes it completely.
