Perhaps it's unfortunate that not that many native born Americans have had the opportunity to converse with immigrants from the Soviet Union, the other Iron Curtain countries, or Cuba. They generally have a good handle on what the Obama regime is all about, and when they obtain American citizenship, they vote overwhelmingly against 'Rat candidates.
But even if you have never had this opportunity, knowledge of world history should teach you that republics tend to become decadent and to self-implode and morph into authoritarian regimes.
Yes, those republics didn't have our Constitution or legally armed populations, however.
These are huge differences that would stop usurpers, communists and other vermin from enslaving us.
Our founding fathers empowered us through the Constitution and the second amendment to protect our Republic. If we choose to squander that, a lot of people would have died in vain.
