Only when we're forced. There's an ego problem with military acquisitions, people want big fancy things. When million dollar missiles are outmatched with thousand dollar drones and that becomes an actual threat is when these things change.

It's fascinating seeing the nature of warfare literally changing before our eyes in Ukraine and still everyone's focused on building big beautiful weapons
