Thatbis definitely an idealistic strategy on its own…it is close to an actual anarchist strategy called syndicalism, also prefiguration. However most anarchists also believe in using other strategies on top of that. And as you said, power is control over others. The people in power are not the ones who have the nukes or the buttons to launch them. The people who push the buttons have a lot more to lose in a revolution by pressing the button than the people in power (because the people in power will lose everything either way). Now do I think calling their bluff is a good bet? Yes. Do I think its enough on its own? No. I think an important thing that is being left out is that those in power are not going to order the buttons be pushed at the slightest hint of revolution. They will wait until all hope is lost. Which means before that point, seizing nuclear launch sites and anti-nuclear defenses is a priority. The dilemma is not between status quo and nuclear annihilation. Its between status quo (with possible nuclear annihilation anyways), or revolution (with possible nuclear annihilation if we fail in a very particular way). To me thats a much easier dilemma to choose from.
