After LINEBACKER 2, US had to withdraw its troops coz they lost so many B-52 and their pilots refused to fight any more war wt VN.
Unlike Iraq, we r good at rebuilding our nations from ashes, we were under CN's occupation for 1 thousand years, suffered the Mongol invasion 3 times (they also completely destroyed our capital ), fighting against CN-France after that, so US wont make any change, we will still survive as usual
And they still have to withdraw even they r also good at guerilla warfare due to military budget cut, u think US soldiers will still fight with No salary ??
Yeah, Ah Q never wanna listen to the Truth, but bad ending will teach him a lesson.
VN has been expanding our territories for century to become big and strong enough to counter all threat , after 1979, we successfully took the control of Laos-Kam's military forces, So,.there is No reason for us to stop our expansion when we r still too small and weak to counter CN-US
