Guns owned by civilians in the U.S prevent a worldwide Dictatorship

Why haven't China or Russia invaded the U.S. yet? China has 1.4 Billion people in itself.
Russia has been at odds with us since 1917 when Communism first started there. We have been Competitors.

Why haven't Russia or China invaded with their armies and taken over America because we own more private weapons than any other nation on earth.

And as long as we all have these weapons and bullets at home if they invaded we would pick them off just like we picked off as snipers like we did when the British invaded in 1776 and before.

Any country would be "OUT OF THEIR MINDS" to think they could subjagate the American people as long as we have  guns. Americans own 48% of the privately owned guns on earth and in regard to preventing a worldwide dictatorship this is a good thing.

It would be in the interests of China and Russia to completely disarm all Americans so watch for funding from Russia and China trying to make rifles especially illegal here in the U.S. in the future.

Track where the money comes from from people wanting Americans to disarm especially now.

Any weapon that could be fitted with a sniper scope where you could pick off invaders from 100 to 500 yards or more they would want to eliminate.

I'm glad that most U.S. firemen and Police officers and soldiers keep these kinds of sniper rifles at home so we cannot be successfully invaded by ANY Army from anywhere on earth.

If they invaded us we would just pick them off one by one at a distance until they all were dead.
