nuclear war china

Tensions with china have evolved into armed conflict in the pacific. The chinese have had enough of the american presence in the south china sea and have decided to launch decapitation strike against american bases in the region. NOTE: this scenario is my first one. I have tested it a couple of times thus far but the scenario is a work in progress. USE OF WMD's are permited. Please note i am still updating this and it does not run smoothly on my computer another user mentioned this as well I am currently working to figure out why this is happening.
