War is not actually a contest to see who is strongest. If it was, then the strongest nations would always fight to the finish and the weaker nations would always be defeated and utterly subjugated. Clausewitz was not the first person to notice that this didn't always happen, nor the first to conclude that war must be viewed as an extension of politics.

As such, dictatorship and imposition of rule through force has to be considered in light of other political options. Oppressive government does not generally start with an all out war to subdue the populace, using strategic weapons like missiles and bombers. Insurrections are managed with lighter arms not because totally destroying the enemy is not a military option but rather because it is not consonant with the relevant political goals.

The right to bear arms isn't about what you do for all out war -- that's when you move from citizen soldiers to building armies -- it's about trimming the distribution at the lower end and improving the odds of the citizenry being able to make it up the food chain in a reasonable amount of time. (Knowing what guns are actually called is a surprising advantage there.) Even Hitler started small, and disarmed the citizenry early.
