Your position is fundamentally flawed. You stated that VN needs to spends trillions of dollars same as china in order to have a proper military ecosystem and if it can't, then can't have an effective ecosystem to defend itself from china.
The ecosystem that china needs is far bigger and far more expensive than what Vietnam needs because of the large chinese territory and the many threats it faces (India, Russia, Japan, USA, Korea, Vietnam, South china sea.
VN on the other hand, only has one enemy and a small territory that is far easier to defend.
Vietnam needs a far smaller and far cheaper ecosystem than china. Vietnam needs a ecosystem tailored to its needs, not a copy of china's ecosystem. Vietnam can concentrate ALL its military resources to face the one threat, china can only deploy an small part of its military against Vietnam since it needs to have most of its forces in the border areas of all those many other threats.
VN does not need a nuclear ecosystem, china does, that's just one of many differences.
Vietnam is steadily building the ecosystem that it needs.
The Vietnam People's Army has utilized satellite communication for the military since 1998, with 4 VSAT stations for the Navy and another five for the air force and army. That was the first step in building the unified command and control system of the 'C3ISR' (Command, Control, Communications, Intelligence, Surveillance and Reconnaissance). The integrated C3ISR network will be finished in a few years. Vietnam has already produced small satellites and is steadily building bigger and bigger satellites to satisfy its needs. Military data link by satellite is already operational since 2008.
Are you aware that VN is building a sophisticated network of radars specifically dedicated to the detection of stealth aircraft as preparation for when china deploys the J-20?
Instead of boasting about the chinese ecosystem (which is way inferior to the one from USA by the way), I suggest you work on fixing all its holes because it has plenty, just to make a point, the chinese radar network in china's coastline (which happens to be the most important area of it) has big gaps between radars that allow US aircraft to penetrate undetected into chinese airspace.
So much for the multi trillion dollar chinese ecosystem, even VN's radar network is better than that.
The fact that you said that there is no difference between Sadam's military and Vietnam's military shows how little you know about the VPA and unlike China's PLA that has a well built reputation for grossly exaggerating its military capabilities, Vietnam on the other hand, keeps utmost secrecy.
I already made the points that I needed to make, I'm not getting into endless debates, I'm in the middle of traveling, I'm done with the subject, ok? Bye Bye.
