Funny that you should mention Los Angeles in the context of turning the tide in such a conflict.
The Chinese military does, too, as you know.
I believe that if Red China does attack Taiwan it will come like a theif in the night. The war will be won in hours, not days. There will me those in Taiwan who will welcome the Red Chinese with a parade. They will also, I feel, only attack if America is distracted someplace else in the world. They don’t want to lose their biggest customer.
