Your examples are kind of hilarious. Viet-cong for example were south Vietnamese guerillas actively backed by north Vietnam, a socialist state allied with the Soviets. Your examples of failed anarchists were crushed due to being under equipped are also funny, if only they'd increased industrialization.

And yes states lose wars of course, against other states orassive uprisings. All successful uprisings the go onto establish states and then survive.

But how many anarchist groups have succeeded amd then survived.

It's a bit like saying professional tennis players are pointless and amateurs are better because they get beat by other professionals. It's a bit funny.

But hey, if you can look me in the eye and honestly tell me you think an anarchist Russia would have survived the Nazi invasion I would find it interesting
