Ahh, how we think we know it all. The fact is that things that we face in this day and age were things that were faced in history. We have forgotten our history because we choose not to study it. We are the same humans though, with the same human tendencies. It is one of the reasons our constitution was written down, because our founding fathers recognized human weakness and their leanings towards infringing on others' rights.
Read these words from Marcus Tullius Cicero, written over 2000 years ago, on internal treason and subversion. They were written about Rome, but they could have been written yesterday about America, if we actually had a politician who would call out the truth of what is happening.
"A nation can survive its fools and even the ambitious.But it cannot survive treason from within.
Marcus Tullius Cicero
An enemy at the gates is less formidable, for he is known and he carries his banners openly against the city. But the traitor moves among those within the gates freely, his sly whispers rustling through all alleys, heard in the very halls of government itself.
For the traitor appears no traitor; he speaks in the accents familiar to his victim, and he wears their face and their garments and he appeals to the baseness that lies deep in the hearts of all men. He rots the soul of a nation; he works secretly and unknown in the night to undermine the pillars of a city; he infects the body politic so that it can no longer resist. A murderer is less to be feared.
The traitor is the plague."
