If a scenario like this were to occur, in fact the US CBGs can
be a big diversion from other allies which can knock out vital
installations inside mainland China while she is focusing her
top-end weaponry on the CBGs off her coastline.I wouldn't bet on US
getting involved with China alone...Anyway, I think China wouldn't
underestimate a CBG.Furthermore, in the event of a war, it's best
hoped that cooler heads will prevail and not a single WMD is used
by either side, for their response would be disastrous.
Here's just a brief look on a typical CBG.Note that China might be
able to overpower the SPY-1 radar by saturation bombardment but
that still leave them open to the air squadrons that will be in the
air before the first PLA missile is inbound.These are just my
views..Anyone care to comment?
