Israel is not the one speaking this part. It is still the kings of the nations speaking. "We" is the kings. "He' is Israel. It is also not wounded for our transgressions, it should be wounded FROM or BECAUSE OF our transgressions. Israel in exile has suffered under the kings of the world. It is their crimes that caused the sufferings. The pogroms, the Holocaust.
The preceding chapter is the Prophet speaking, relaying the words of God:
Isa 52:3 For thus saith the LORD...
And the voice does not change in any way throughout the narrative, so it is more logical to conclude that the Prophet continues speaking. There is no indication that suddenly the Prophet takes on the voice of the King's perspective.
Also, Israel was not crushed for the crimes of the Kings, but for their own crimes. The apostasy of the Jews during and before the war was great and profound. As I've noted previously, even the High Priest at that time served illegally, and the Temple was profaned by the Zealots. The scripture also says, according to you, that Israel was sentenced to prison and taken as a lamb to slaughter, even though He committed no crime and there was no word of deception from His mouth. Yet, that certainly wasn't the case with the Zealots. None of this fits for Israel.
In each instance, whenever Israel was bound and set into exile, it was always as a consequence of its own crimes against God. He promised blessings for when they followed the law of God, and punishments for when they did not. There is never any instance where Israel is punished for a crime it did not commit, and surely the destruction of the Temple could only mean the highest crime possible had been punished.
Furthermore, around the time that land became a province, there was only one Shiloh who was born, and that is Christ:
Gen 49:10 The sceptre shall not depart from Judah, nor a lawgiver from between his feet, until Shiloh come; and unto him shall the gathering of the people be.
So all these things have come and gone, and yet there is no evidence that Israel could ever fulfill that prophecy. I will not claim that the Jews deserved the hate of the socialists, both national and international, or the Muslims who were earlier, or the Catholics or anyone else who persecuted them. But I also will not believe that those murdered Jews were doing the Gentiles a favor somehow!
Isiah states earlier that Israel received a double portion of our punishment for our sins. Why is this? Israel is to be a nation of priests and priests bear the iniquity of the sanctuary, so Israel must bear the iniquity of the world. The world suffers less because Israel suffers more.
Soon there may be a world war, and it will only be because America is the ally of Israel, which the communists over many years have painted as a great Satan in order to unite the Middle East against our interests. If Israel were to fall, the suffering would be world wide, as the war would be universal. And I do not see how World War 2 was confined only to the Jewish people. I seem to recall millions of other people also dying, though the Jews were the special target of the Holocaust.
Again, history does not seem to back up these statements. If they were true, killing a Jew each day would guarantee a lot of peace. The Muslims, however, enjoy variation in their murders and do not confine them to you all.
All your doctrine is doing is taking the prophecy of Jesus Christ and applying it to the entirety of Israel, while at the same time ignoring the role of the Messiah.
