In a metaphorical sense, Ukraine is the scrappy 'startup' aka highly maneuverable speed boat that can turn on a dime, and the US Department of Defence is a cargo ship that takes years to execute a single turn. The drone playbook is out there, plain for all to see but there are too many entrenched stakeholder interests and incentives for the US to emulate the Ukraine drone playbook. You think the US would establish underground 3D printing drone factories? That would be an insult to its military industrial complex, and a tarnish on its sterling prestige, n'est ce pas?
