easy.
Nobody is coming after you with a tank or a fighter jet.
If you will be lucky you will be the first or second one who they will come after and you might get a lucky shot off. On the other hand as Iraq is showing an individual with a firearm isn’t going to stop a squad of soldiers with support.
That is why Saddam didn’t have gun control in Iraq I believe. IED’s that are currently not covered by the Second Amendment on the other hand is very effective over there.
I figure most of the 2nd Amendment my gun will defeat the government types will be dead, surrendered, or hiding within a month of any revolt against the government.
