The "Final Solution" in Herzl's mind was the creation of a Jewish state which was later carried out to fruition by Chaim Weizmann with the help of Arthur Balfour's Balfour Declaration. From Balfour's perspective, the Declaration was a way to move Russian Jews OUT of the UK as Russian Jews had recently overthrown the czar and were also carrying out a civil war in Weimar era Germany leading to the rise of the NSDAP. (Fun fact, the US had already been overthrown by the same people with the creation of the Federal Reserve in 1913.) Speaking of the NSDAP, why did Hitler offer the Jews safe transfer to Palestine through the Haavara Agreement even after world Jewry declared war on Germany in 1933? BUT, you know what they say. "History is written by the victors."
