America has, for decades, has been trying to bilk Ukraine into forgoing free Soviet surplus to buy NATO-standardized equipment, only to remotely disable their material while they're using it. Because America was so fickle in providing defense, we've guaranteed that all future peace treaties (eg. one in Ukraine) necessitates direct American intervention, and not vague "security" agreements. That's probably why Trump is brooding over his options right now instead of arranging a ceasefire - he can't get peace without trading away something absurd like US naval assets or direct satellite intel.
1991-1994: They nuke Moscow.
1994-present day: American strategic deterrence takes over.
If any part of that is unclear to you then I urge that you reread the Budapest Memorandum on Security Assurances and return to the discussion with the rest of the context.
Anduril does not manufacture strategic deterrents. If you think they're the solution to the Budapest Memorandum then you're the sort of armchair YouTube General that the Army filters out in officer school. It's not hard to understand, anyone can Google the difference between strategy and tactics.
Edit: oh I see, you only support strategic deterrence which equates to “standby until we have to nuke them.”
