Barack Obama and Eric Holder did not create a weaponized DOJ and FBI; the institutions were already weaponized by the Patriot Act. What Obama and Holder did was take the preexisting system and retool it, so the weapons of government only targeted one side of the political continuum.
This point is where many people understandably get confused.

In the era shortly after 9/11 the DC national security apparatus, instructed by Vice President Dick Cheney, was constructed to preserve continuity of government and simultaneously view all Americans as potential threats. The Department of Homeland Security (DHS) and the Office of the Director of National Intelligence (ODNI) were created specifically for this purpose.
After 9/11/01 the electronic surveillance system that was originally created to monitor threats from abroad was retooled to monitor threats inside our country. That is when all of our electronic ‘metadata’ came under federal surveillance.
That inflection point, and the process that followed, was exactly what Edward Snowden tried to point out.
What Barack Obama and Eric Holder did with that new construct was refine the internal targeting mechanisms so that only their political opposition became the target of this new national security system.
The problems we face now as a country are directly an outcome of two very distinct points that were merged by Barack Obama. (1) The post 9/11 monitoring of electronic communication of American citizens; and (2) Obama’s team creating a fine-tuning knob that it focused on the politics of the targets. This is very important to understand as you dig deeper into this research outline.

“This is no small thing, to restore a republic after it has fallen into corruption. I have studied history for years and I cannot recall it ever happening. It may be that our task is impossible. Yet, if we do not try then how will we know it can’t be done? And if we do not try, it most certainly won’t be done. The Founders’ Republic, and the larger war for western civilization, will be lost.”
Our Father, who art in heaven, hallowed be thy Name. Thy kingdom come. THY WILL BE DONE, on earth as it is in heaven. Give us this day our daily bread. And forgive us our trespasses, as we forgive those who trespass against us. And lead us not into temptation, but DELIVER US FROM EVIL.
Before getting to detail, first it is important to emphasize a point that doesn’t get attention domestically. Democrats are exceptionally weak on all aspects of foreign policy, specifically because their modern ideology is based on hypocrisy of a stunning magnitude.
