Lol the 2nd amendment isn't about having the best weaponry or having the best vehicles. The 2nd amendment guarantees manpower and logically thinking, a state ran military of 500k is always going to suffer defeat against 300 million citizens who are all armed to the teeth with assault rifles. That's the idea our founding fathers had.
LOL. Is this some sort of alternative facts version of history from Prager University or did you sleep thru civics class?
Did you or did you not previously indicate "the whole point of the 2nd amendment is that the citizens are proportionately armed to the government"? Yes, in fact, you did. The US government is armed with such firepower that the 35% of US adults who own a gun, 60+% of whom own just a handgun, would s**t themselves in the face of it given their meager proportional defenses.
It's clear to me you have a very poor understanding of not only the history of the Second Amendment but also of the practicality of US citizens defending themselves against the firepower of a fully engaged US military - if that were to happen, which it isn't given we have an all-volunteer force that's not remotely likely to turn its weapons on the full citizenry. What you are employing is not logic, it's fantasy in defense of an indefensible premise.
All that aside, Amendments to the Constitution as originally written were for their time and place. NONE of the Founders expected them to be immutable, evidenced by the very fact that they allowed for Amendments in the first place.
