"I find it hard to believe that the Rothschilds rule the world. If they truly did, they would have prevented the massacre of Jews in Europe during World War II."

You misunderstand the Sabbatean/Frankist cult. It was the Rothschilds that funded Hilter's rise. It was the Rothschilds that profited from destroying European Jewry that did not want to emigrate to Israel. It was the Rothschilds that funded and massively invested in Bolshevism that created the threat of Communism that forced the German people to rally to Hitler to prevent being genocided as had the Ukraine and Belarus in the Holodomor, and the purge of the Kulaks later under Stalin. The stated purpose of the Rothschilds is not to benefit Jews, but to commit so much evil that the Moshiach will return sooner than otherwise. They claim they are extorting God, but this is only one layer of the endless layer of false stories they tell to justify their pathological and implacable design for global conquest.

They are psychopaths, my friend, not people competent to build a society. People are just objects to them, and that includes Jews. In truth I do not believe the Rothschilds actually believe in God at all, but use every religion and philosophy as a tool to deceive more people and enable themselves to profit. They only work together now because there are still hosts to parasitize. Each of them intends to betray the others to become THE overlord of the world. When they estimate the time is right to be the first to move, then they will begin destroying each other. Sadly this will only happen after significant horrific destruction of civil society has happened, and many millions of people will suffer and die. Happily, this will happen while many people still live, because the second traitor will be the first of the losers, and everyone of them has an existential need to be the first one to betray the rest, which will spare many millions that would otherwise be destroyed.

You correctly note that Jews persecuted Christians. After the destruction of Rome, primarily through the same corruption that is today being imposed on Western Civilization by Jews, Jews continued such persecutions, albeit covertly because they were outnumbered. By poisoning bread in mills and bakeries, and wells, Jews created genocidal levels of death and suffering that is blamed on disease today. When Jews were ejected from countries where they had been poisoning the people, the plague ended. ~1/3 of European Christians died by these terrorist acts.

"I believe the Jews who came to the New World and founded America were Christians..."

After the Reconquista of Spain, many Jews became Conversos (whom pretended to convert but secretly continued their Judaism), both in Islam and Christianity. In 1492 the Spanish Crown evicted Jews from Spain, and this created many whom pretended to convert to Christianity and soon took over the Jesuit order. However, the removal of Jews enabled Spain to prosper, and 1492 is noted as the beginning of Spain's golden age.

In the USA Jews owned the vast majority of African slaves. Very few, ~2%, of Christians owned slaves, as it is contrary to Christian principles. John Smith famously preached to his fellow Quakers to free their slaves and free themselves of the moral hazards that came from profiting on the backs of men treated as property. Jews have always been involved in the slave trade, into the depths of prehistory. Amongst the Christians that founded America were families involved in banking, such as Alexander Hamilton, and by this means Jews did immigrate to the nascent country, particularly involving the slave trade, and agriculture in the South based on slave labor.

"I believe that the one who rules the world today is Jesus!"

In 2 Cor 4:4 Paul writes: "Satan, who is the god of this world, has blinded the minds of those who don’t believe."

"What do you think are the differences between Judaism, Islam, and Christianity?"

There are so many sects of each branch of Abrahamic traditions that the differences are impossible to characterize. I have learned that what we are told is not true. People continually and always seek to use religion to create political power, and I believe that causes all religions to be more alike, because they are used as weapons and deception to turn deceived people into money farms for corrupt and evil priests. I think this is the signatory feature of Abrahamic - and all religions - today.

The essential principles of righteousness are present in the core teachings of most religions, including most non-Abrahamic religions with panteons of gods. All of them have a creator God just as Abrahamic religions do, and the pantheons are more like angels or saints than the creator in monotheist doctrines. I think humanity has been so indoctrinated and propagandized in every culture and religion to be useful to Machiavellian warlords that the essence of righteousness at the core of all religions has been utterly suppressed and replaced by teachings that enable parasitizing the faithful for wealth and power. Therefore I think differences between religions are meaningless, because it is the identical duplicity of priesthoods to create compliant cash cattle and cannon fodder for warlords that is their most important feature.

Thanks!
