asymmetric warfare can is open now. Any US adversary must be building sleeper cells in the continental US armed with drones from walmart/bestbuy ready to drop a grenade that will burn big and expensive planes/submarines/aircraft carriers, possibly even rocket silos or other parts of critical infrastructure. If I were Iran/NK, or China, that would be my top priority, so that I could retaliate if USA attacks first
