Before sending in ground troops, I think we need a softening up barrage into the centers of resistance like SF and LA. In SF, the Russian Hill area would be a good place to commence and in LA anywhere from Malibu to Santa Monica would suit me fine. If a few fall short into east LA, nothing to be lost with that either.
SF areaused to be a great Navy town with Treasure Island, Mare Island, Oakland Naval Supply, and Alameda NAS. Today it is a band of electron pushing nano second junkies all of whom seem to be commie elitists.
I wouldn’t target SF itself. Most of the real wealthy power brokers abandoned SF for Marin, Santa Clara, and other locales a long time ago.
No, I would simply nuke Silicon Valley. The world would instantly become a better place. Your target selection for Southern Cal is right on the money however.
