Once the gun was invented, there was a very short window of time where you could win with an army of swordsman, before it became a laughable concept of honor before reason leading to your death.

That's what the Right has failed to understand for generations now. Once these political weapons are on the table, you can't just pretend they don't exist. You can only use them to wipe out your enemy (and then struggle to go back to limiting yourself) or sit there and be wiped out.
