Curious how this strategy updates now that drones make war even more asymmetric. A drone worth $100 can destroy a tank worth $1 million or a helicopter worth $10 millions. It's theorized that a drone swarm can sink an aircraft carrier group, which costs billions of dollars. New technology used for war such as lasers or AI will only make war even more asymmetric. So essentially, big-countries can't attack other big-countries because of nukes and MAD (mutually-assured-destruction). Big-countries can't attack small-countries because of asymmetric war. Small-countries can't attack big-countries for obvious reasons. So, the only war left is small-countries vs small-countries.
