The most common theory among conspiracy theorists who believe in Jewish conspiracy is that the creation of the state of Israel is the result of a conspiracy by Jewish leaders to bring the Jewish people back to the lands from which they were driven 2000 years ago. Jewish leaders would have gradually taken control of all Western countries with the aim not only of being masters of the world, but also of recreating Israel. Once this is done, an additional objective would be to make Israel the world's capital. Moreover, Freemasonry is said to be a creation of Jewish leaders. It would be an intermediate power created to have the elite of the goys applying the orders of Jewish leaders.
That's what I thought until a few years ago.
On the surface, it seems to make sense as an idea. Indeed, there appears to have been a takeover of the various European countries by Jewish leaders over the past 500 years. The first country would have been Italy with the Medici, then England with Cromwell, then probably the USA during the colonization, then France with the 1789 revolution, then most European countries with the takeover of Europe by the French under Napoleon, and finally Russia in 1917. And for Freemasons, some say that Freemasons' rites are Jewish from A to Z.
As for the desire to recreate the state of Israel, it seems logical, since, according to their sacred books, it is the land promised by God and they actually lived there for several centuries before being driven out. And since Jews have remained very religious for centuries, it is normal that they wanted to return to the land that God had promised them. However, before the end of the 19th century, we don't have much evidence that they were making a plan to get back there. But from then on, things became clear (writings by Nathan Birnbaum from 1882, book by Theodore Herzl "The State of the Jews" in 1896, Balfour declaration in 1917, San Remo conference in 1920, etc...). Moreover, we can think that the desire to take power in Europe, then in the world, is a strong indication of this desire to return to Israel, beyond the mere desire for domination.
