We don't need to actually starve them. The CCP will not be able to fight the war all out. They will need troops at home to guard against civil unrest.
The CCP leadership is already twitchy about people standing around, silently holding blank pieces of paper. One guy, Peng Lui, with one long banner on an overpass last year scared the hell out of them.
Just the act of starting the war will mean their demise no matter how the fighting goes.
