I see the logic...but if the United States became hardcore tyrannical, that means they don't give a fuck about human rights, they don't give a fuck about what their citizens think....They would fucking destroy Citizens.
Only reason why we had problems with Iraq/Afghanistan is because we didn't go on a killing spree, we were trying to work with the people....If they truly wanted, they could of carpet bomb all of them, and massacred them
Same goes with Vietnam...The people grew tired of the war stateside, so the United States just said fuck it, it's an unpopular war...again they could've kept the war going and going.....Eventually the United States would've won.
No doubt Civilians would make it harder for this mythical Tyrannical government...But the insurgency would lose if the government was truly hardcore tyrant like.
and I support the 2nd amendment btw.
