Western support for the establishment of the state of Israel long preceded WWII. from memory the Balfour declaration was made in 1924.
There was nothing about an exclusive "Jewish state" in the Balfour declaration.
The Jewish banker Rothshild just demanded from the Brits that they would have to conquer Palestine and allow the Jews to settle there, if they wanted to get any help from Jewish bankers. Great Britain was in a desperate situation, they were losing the war, and they were ready to sign a peace agreement with Germany.
Jewish bankers used their influence and promised to British government that they would involve the USA into the WWI, if the Brits conquered Palestine.
But in this declaration there was nothing about a separate Jewish State, and Brits would not have signed a declaration that guarantees to the Jews a separate state on the cleansed Palestinian territory. Brits were fooled by the Zionists, they tried their best and fought the Jewish terrorism in Palestine, losing a lot of British soldiers who were killed by Jewish extremists in Palestine.
If Brits knew what will happen after they signed the Balfour Declaration, they would probably signed a peace treatment with Germany.
My sympathy and support for Israel does not rest on the holocaust but on its nature as a democracy and a decent state: the only one in what is more properly called the Near East.
Israel was created via terror, Menachem Begin was a bloody terrorist who killed nonsenses British soldiers.
The first leader, who recognized Israel, was the mass murderer Stalin, and Stalin was the one who voted with 5 votes for the partition of Palestine, and he was the first to help Israel with weapons.
After that Zionists started their ethnic cleansing of Palestine, and replaced the native Semitic population of the region with migrants from different countries.
This was a violation of international laws, ethnic cleansing and the replacement of the population is prohibited by the Geneva Conventions.
But due to the influence of the Israel Lobby in the USA Zionists can get away with their crimes.
Israel is an apartheid regime which goes on with ethnic cleansing and land theft, the Israeli government is still promoting segregation.
How can somebody in his right mind call Israel, which has a racial "law or return" (only Jews are permitted to migrate to Israel, but the expelled Palestinians are prohibited from returning to their homes) a democracy?
Do non-Jewish Palestinians have the same value in Israel, like Jewish Israelis?
Would American Jews be happy, if they were treated in the USA like Israeli Arabs are treated in Israel?
Would Jewish Americans be happy, if Christian Americans called the USA a "Christian State" and forced the Jews to pledge allegiance to the "Christian state"?
Would the American Jews be happy, if in the USA only marriages between Christians and Jews were illegal, like it is the case in Israel?
Would the American Jews be happy, if white Christians had a privileged right to migrate to the USA?
In Israel, white Jews have a privileged right to "return" to Israel!
Can you answer these simple questions?
