Of course, the ChiComs would immediately bomb Jimmuh's canal, making our supply route that much more difficult!
I think even the Dummies will be surprised how many NEW friends we have if the Commies attack. If we go down there is nothing in the way to keep the commies from moving in on Japan, Asia, Eastern Europe.........
I believe we have five aircraft carriers and supporting ships stationed on the west coast and in Hawaii. The Panama canal is not a factor any more and our carriers are too big to fit through the canal anyway. I don't know for sure, but I'll bet we have two carrier battle groups within seven days of Taiwain at all times.
The Panama Canal is largely irrelevant to the US military at the moment, and not particularly relevant to the US economy, and it being inoperable wouldn't matter much to the US in a war at all.
