ISIS may be more ruthless, but I wouldn't say they're better fighters than the VC. The VC was pretty intelligent and had good leaders. ISIS has beaten a bunch of half assed soldiers, who obviously didn't want to fight in the first place, in places that they have at least a modicum of popular support because of a braindead Iraqi president.

Unfortunately what this is is the Iraq War all over again, which did have obvious similarities to the Vietnam war in terms of the type of war as opposed to the level of opponent. A prolonged engagement against a hidden enemy blending with the populace basically turning into guerilla warfare/an insurgency.

I wouldn't overrate ISIS militarily.
