You're so far off it's not even funny. The British robbed his country blind because it was divided. It was splintered in dozens of small states the British pit against each other.

Britain could have never conquered a fully united India, the same way it couldn't conquer China (though it chipped away at it for the better part of a century).

Regarding invasions, who's going to invade you? Canada? Mexico? Even if someone wanted to/could, they wouldn't be afraid of your personal weapons but instead they'd be afraid of your nuclear arsenal, of the largest navy, airforce and military budget in the world. A military budget equal to that of the next 10 countries.

All your guns do is promote unreasonable policing practices where people are shot on sight cause you never know if a suspect is carrying a gun. Oh, they also have a great side effect: if you ever have major internal problems or say, a civil war, millions of people will die cause everyone has a gun. Not that a lot of people wouldn't die either way, after all we've been using knives and machetes for millenia, but there's a reason all of today's armies use guns as the main infantry weapons.
