yes... losing California does not make a huge dent on weapon manufacturing. At least the weapon factory plants in mid-west will have more manpower especially from fleeing Californians.
which is precisely why you shouldn't attack Hawaii first. You attack mainland first then hit Hawaii. Once you attack mainland.... the damage's already done and it's too late for navy to bail them out.
Major shipping ports on West Coast (there are over 29 ports) -
California - Los Angelos, Long Beach, San Diego, Oakland, so on...
Washington - Seattle, Tacoma
if I remember correctly - approximately 45% of Chinese products go thru West Coast via shipping ports. Now you see why I picked California and Washington as first target for Chinese? Simply hide military inside gigantic cargo/tanker ships. worse of all.... our military (especially tanks/strykers/etc) cannot be mobilized quickly enough thru major cities. California National Guards will have to defend long enough to evacuate the Californians. That's how we'll lose our Western states.
yup that is the most likely scenario rather than invasion lol... but it does make a nice movie/game, eh?
