Ok mastermind i'll give you a much better source to look at, this guy pretty much uses the Tanach, basically the english bible has been tweaked a little bit to make it sound like its Jesus:

There are quite a few parts to this (links at bottom/top to next part), so you should read all of it before jump to a misinformed conclusion.
Also your mistaken about the Isaiah talking about Israel being a medieval creation, that site above explains this in the last section.
Kurieuo, i never converted to Judaism, I would be considered a Noahide. One who follows the covenant God made with Noah and his offspring, the gentiles, are explained in this site:

Also I find no problems with Jesus's geneology as I don't believe Jesus was born of a virgin, so as far as i'm concerned he fulfilled that Prophecy, however all we have is he rode on a donkey and he's a descendant of David. I'm sorry but many people at the time of Jesus could easily fulfill these two requirements.
Also Kurieuo, you can't simple use the resurrection to mean someone is the messiah. Elijah asked God to resurrect a dead boy and God did, does this mean that boy is the messiah? NO, in fact i really have no problem with Jesus resurrecting, it just means God used Jesus for a purpose. This purpose obviously is multi-faceted, but part of it would be to bring the gentiles closer to the Truth being the Torah/Tanach.
Also let me explain how the Gospels aren't really reliable:
they replied, “for this is what the prophet has written: 6“ ‘But you, Bethlehem, in the land of Judah, are by no means least among the rulers of Judah; for out of you will come a ruler who will be the shepherd of my people Israel.’[d]”
Ok lets examine and compare this with the Tanach version:
"Now gather thyself in troops, O daughter of troops: he hath laid siege against us: they shall smite the judge of Israel with a rod upon the cheek. But thou, Bethlehem Ephratah, [though] thou be little among the thousands of Judah, [yet] out of thee shall he come forth unto me [that is] to be ruler in Israel, whose goings forth have been from of old, from everlasting....And he shall stand and feed in the strength of the LORD, in the majesty of the name of the LORD his God; and they shall abide: for now shall he be great unto the ends of the earth. And this man shall be the peace, when the Assyrian shall come into our land....and they shall waste the land of Assyria with the sword..." (Micah 5:1-6)
Also here is how the NIV translates that Micah verse: "But you, Bethlehem Ephrathah, though you are small among the clans (or, rulers) of Judah, out of you will come for me one who will be ruler over Israel..." (Micah 5:2)
Ok here we see Bethlehem Ephrathah most likely referring to a clan. Micah is really talking about a person who will save them from the Assyrians. Nineveh, the capital of Assyria, was destroyed and Assyrian power ceased to exist 606 years before Jesus was born. Jesus had nothing whatsoever to do with the Assyrians. This is not a messianic prophecy!!
I can't say how reliable christian think tank is as it fails to realize that this prophecy is not of messianic nature. Apologists also claim that Matthew the apostle was an eye-witness to many of the events in the life of Jesus, but a substantial body of scholarly work strongly indicates that the book of Matthew was not authored by apostle Matthew. So frankly, Christians need to stop linking every prophecy ever told in the Tanach to Jesus, its quite misleading.
