Even if one agrees that a "strong US military" is beneficial this doesn't neccissarily includes all forms of warfare.

For example I can argue that a strong military is important to defend the country (or maybe even the West or whatever) while a military made out of drones and robots mixed with AI, driven by a Space Force is too easily deployed in combat, since risk on own loss is low, while the opponent might see civilian casualties, causing more harm than good.
