The Vietcong's intention was infinite -- our intention was finite. They would fight forever because it was their country and their children; we had to get home for Christmas.If we aren't willing to do what the Romans did - eradicate whole peoples who are inconvenient - and I believe we are not, then we shouldn't occupy their countries.
Decapitating an antagonistic leadership without occupation - essentially what the Mossad would do - is another matter.
