The Illuminati reveal their domination by placing their symbols on our currency, ID cards, civic and corporate logos. Their monuments, architecture, hand signs and signals are everywhere. Why do they proclaim their presence instead of maintaining secrecy?
The Illuminati do not see themselves merely as assuming power, but taking BACK what they consider their rightful place and their natural property: being in control of Human Destiny. In their minds, Human history is, and long has been, an issue of war.
The unexpected emergence of Christianity foisted -- or at least very seriously delayed -- a number of Illuminati plans. The accession of Christianity as a major social and political force spiraled out of control so rapidly that the comparatively small numbers of the ancient Illuminati were driven into hiding and secrecy. From this, the blood-feud -- the Vendetta -- emerged.
When the Illuminati publish their presence, it is not so that "normal" people can detect the symbols and formulate what most would see as spectacular conspiracy theories. It is an announcement of expectations of victory, in the manner of a vendetta.
When the Illuminati announce their influence, it is meant to be the voicing of a threat to their enemies and their prey. "We have established yet another foothold. We are coming for you, in due time."
