This is real quick, I have a lot more to say on the subject, but not enough time.
1. ) First and foremost; don't ever go into a war without counting the cost!!! (Thinking it all the way through.)
2. ) We should have known that the commies were weak and pathetic. Spineless vermin who would never in a million years retaliate if we went nuclear. Some may have known this, others were just plain scared. Sad.
3. ) If you go into the fight: FIGHT!!! DON'T HALF STEP!!!
=================================================
This is what I would have done. I don't go into Nam in the first place.
If for some reason beyond my power I had to fight this war, I win hands down within 6 months. There is no way on this earth that I lose this war. It would be impossible. It would be 100% impossible to lose this war if fought correctly.
The first thing I would have done is go up top with B-52's and rained death from above. I would have blown every single bridge, every single power plant, every single manufacturing plant. I wipe out there ports! All of them. I sink all there ships. I let my soldiers fight and I lock the media out of the war. I blow up burn and destroy so much of N. Nam that they vomit tears out of their until they get on their hands and knees and beg for mercy.
And for all you who say "China"! I would not be afraid of China. I just let the world know that I ABSOLUTELY GO NUCLEAR if anyone gets in my way. I let one off the coast of Nam just to make my point. That 100% guarantees the Chinese back off.
Basically I use good old fashioned WWII tactics that just punish with shear violence and destruction so much that the enemy falls to the floor begging for their lives. That is the only way to fight a war!!!
Either you don't fight! <=== this is preferable. Or you fight and smash your enemies face in soooooooooooo bad, he cries and gives up.
Fin.
