There are Jews and those that claim to be Jews and are not. There are Israelites and those that claim to be Israelites and are not. These are also mentioned in the Bible.

Israel, biblically anyway, cannot exist as a land/country. The Israelites have no land to lay their heads, they are scattered. it's all a con, it always has been.

Christ stood to put an end to this for good but they killed him.

It is easier to fool a person than it is to convince them that they have been fooled.
