Those anti-ship missiles can be launched from aircraft, which they have plenty of. They also have several Sovremenny class destroyers capable of launching missles, and several other destroyers and frigates. They have at least 5 nuclear powered attack subs, plus many diesel powered subs for coastal defense. Additionally, they have facilities in the Panama Canal zone, and who knows what they have there. They also have a base in the Bahamas, and again, who knows what they have there under wraps.
I certainly share your concern, in fact you could say that there are many things about the Chinese and their tactics that alarm me. However, their so called airforce consists of vietnam era 'fighter jets' and not one of their naval ships are up to standard with those compared to those in the US fleet. Not to mention that the 'fighter pilots' in the Chinese military do not log a 1/4 of flight training as compared to US fighter pilots. If there were ever a conflict with the Chinese and it involved air power, it would be nothing more than a skeet shoot for our US pilots.
As for the panama canal, that situation disturbs me a great deal but if you think about it...who is it closer to...the US or CHina? Do you know how fast and how many troops we could have there in a short time to take control of that zone? Dont forget, the US has an obligation to "protect" the Panama canal and we arent going to let it go when it serves our national interests.
Can you elaborate please ? Thanks.
