Everyone keep in mind the Illuminati's greatest feat is to make the masses believe they DO NOT EXIST. If for some reason the Illuminati wanted to recruit you into their organization, they are not going to come to you and say "Hi, we are the Illuminati and we want to recruit you into our organization". They will incorporate you into their organization by way of a job, opportunity, loans, position or title you otherwise would never get, etc etc etc. Many people are a part of their organization and are totally unaware of it. Perfect example THE MILITARY. These knuckleheads voluntarily sign up and fulfill the desires of these MADMEN whose goals are to conquer nations, steal resources, get rich (or richer) gain power and control by way of a large group of trained assassins.
Knowing the history of the Illuminati tells you why they remain secret...they don't want it known that their goal is world control, so they slither into banking, media, universities, corporations, government etc etc this way they control EVERYTHING the masses need and want and thereby control everyone and everything. When the Illuminati was in Europe (where the Illuminati began) their organizations were found out (France) and roundly rooted out sending them fleeing into other countries (England and then america) and then world wide to establish their organization and control. Since then the Illuminati has gained control over every newspaper, news program, corporation, politics in every nation, has created armies world wide, has control over military worldwide, has caused all world wars and outcomes, has controlled all depressions and monetary collapses as a way of getting more control, land, money and power. Their influence is extensive and becoming more so. TO deny their existence is to play right into their plan that...THEY DON'T EXIST. It won't be long before they stop hiding and come right out and tell the world they control everything and now everyone is their subject. And since they control everything right down to water, electricity, gas, food etc...the masses won't have much in the for of power to do much should this time come.
