I think , to build a carrierer is not a technical problem, but a political one !
At present , China's threaten theory are everwhere, everyear . Carrier is a offensive weapon, if we build it , what will it leave to other country?
----yes, the Chinese are stronger and stronger, they are comeing to attack us.
Anybody who can tell me how to tell a weapon is offensive or a defensive ?
We bulit nuclear bomb is not to attack any country ,but to prevent us form being attacked. And we have said :we'll not use nuclear weapons first in a war . Does any country who has nuclear bomb ,can say that ? the U.S.A? the RUSSIA ?the France ?.....
Many many people thind a country ,if he grow up , aggression must happen.
We are the country suffered much war . much slaughter, we don't want this happen again , we want peace.
maybe somebody will say: this guy's words just like their government saying.
seems he was indoctrinated heavily .
my answer is no ! that's the words from heart.
