The Watchtower is only concerned with the destruction of the Second Temple in 70 CE. Too often in their literature the Witnesses have misapplied the description of the ending of the Bar Kokhba revolt by the Romans to the fall of Herod's Temple, as if Judah was emptied then and the Diaspora began in 70.
The Diaspora began in 135 CE with the end of the Bar Kokhba rising, and the horrific death toll and descriptions of slaughter the Watchtower often used for 70 CE to typify the destruction of either Babylon the Great or Armageddon belongs to what happened in 135. I know this because according to Jewish tradition (with some historical support) the last Christian bishop of Jewish descent, Judah Kyriakos, is part of my ancestral family tree. There are no reports of him being slaughtered by the Romans nor of him entering Sepharad (modern-day Spain/Portugal) with the rest of the House of David. Tradition has him living until 148, but exactly where he lived his last days is unknown.
The terrorist acts by the Revisionist Zionists such as the Irgun and the Haganah didn't exactly drive out the British. It was the Civil War that did it.
Keeping Israel as a territory under British control was becoming a headache as the outcry of a need for a homeland for the Jews after the world learned of the Holocaust grew louder. The problem only escalated as sympathy from the U.N. and the lines of support for orthodox Zionism and Revisionist Zionist and its acts of political violence began to blur on the world scene.
In an effort to bring peace, the British army began a proposal of "sleeping with the enemy." The Haganah (among others) actually joined the ranks of the British forces for a while when the Jewish Agency/Zionist organizations were fighting to stop terrorist attacks against British authorities.
WIth the breakout of the Palestinian Civil War, Britain pulled out (they were not going to get in the middle of a bloodbath between Arabs and Jews for a slice of desert). They had, of course trained the Haganah, and it was their particular skills and forces that won the war for the Israeli army.
With the sympathy for the Jews having grown even wider while the Civil War played out (it was at the same time that the full details of Hitler's "final solution" and the type of suffering the Jews had endured in the concentration camps and the number who died were circulating around the globe by radio and newspapers and magazines and newsreels), the birth of the modern State of Israel met with little resistance on the 14 of May 1948.
Currently, however the State of Israel is under a government similar to that of what we find in America now, only a bit more far to the right and if the president had a heavy Fundamentalist slant to all he did, favoring only the strictest Fundamentalist Christian churches. You are still free to be who you are and worship as you wish, but right now if you aren't a member of the right Jewish denomination, you can't get in if you are a Jew who wants to claim your right to a home in Israel (Orthodox only). And even though it was established as a secular state ensuring the freedom of the Jewish religion, currently it acts as a Jewish religious state out to crush secularism.
And I don't have to tell you about the corruption charges against the leadership that has been raining down like...well, like the Ten Plagues on the current Israeli administration.
Just thought I would add this too.
