I read recently that Americans buy enough arms every year to equip the Chinese and Indian militaries combined. That's EVERY YEAR! Add to that the approximately 1.1 billion rounds of ammo sold in the US each month and you have a force that no country on earth, or group of countries for that matter, could ever successfully invade by force of arms. In spite of that fact the invasion of the US is ongoing and continues because we refuse to close the southern border. Our enemy is here already and re-enforcements arrive daily.
