I did not say just to be expediently cruel to the South Koreans. That is the potentiality that the South Koreans know and I know they know that because I trained with their ROK Marines.
Yes, but that may be the last thing that ROK generals would consider. Surrendering capital city could down the defending army's moral, and that's an unlikely situation for ROK armed forces to leave Seoul.
The North Korean troops will float over the DMZ mines?
The NK troops will be so stupid to not to think about how to cross DMZ minefields before invading it? The french built Maginot line with minefields, trenches, tank traps, and fortified gun bases, that didn't help France to hold German invasion in WW2 through unguarded Ardennes. There will always be a way to cross that minefields and do you think NK is that stupid?
And people continues to believe that Americans are stupid when they are ignorant of the history of the thing they uses to criticize Americans.
It was the politics of the Vietnam War that allows the trail to have respite from air attacks. And do you know what happened to the Viet Cong after Tet 1968? Almost destroyed in South Viet Nam. The military bottom line is that the trail was vulnerable and could have been completely severed
if politics were not involved.
Politics make up the secondary factor of any successive attempts in the battlefield, the main point is the NVA men were able to deliver such numerous amount of supply to the Vietcong, so it will not be an impossible thing for DPRK military forces to replicate the effort done by the North Vietnamese.
I know that the Tet offensive ended up a failure for the communist Vietnam, but back to our discussion, the effort (including sending the supplies) to make the Tet offensive become a reality was successfully done by the NVA.
Funny to note the fact that you mentioned politics in your previous paragraph, and then you said that the absence of politics would completely destroy the supply lines through trails. War is a continuation of politic, every war is backed by politic, what makes you think that politics will not be involved in the future Korean war?
