"A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed."
Few people actually show the text. When England's government became oppressive and unfair to the colonies, it was necessary to raise an army of Militia soldiers to defend and fight for freedom. The authors of our Constitution knew, first hand what it was like to stand up to a bad government that was in power. In their wisdom, they kept this check in the foundation of the new government they were forming. This amendment was meant to keep a balance between the population and any government (like England) that could become corrupted.
Consider for a moment, Nazi Germany. Their government was a democracy similar to England. Of the 12,000,000 exterminated, if only 1% of them had firearms, there would be an armed force of 120,000. Think about what a difference it might have made.
It wasn't until after the war that Nokmim (Hebrew: הנוקמים), also referred to as The Avengers or the Jewish Avengers, a Jewish partisan militia was formed. Forming a "militia." Sound familiar? Pity it was AFTER the war.
