Not the first proposal. Among others:
In 1820, Grand Island in the Niagara River was proposed as a homeland for the Jews, to be called "Ararat”
The British planned to give a portion of British East Africa to the Jewish people as a homeland. The offer was first made in 1903.
Hitler wanted to move the Jews to Madagascar.
God gave the Jews a homeland. It belongs to them. They should stay there.
Some Israeli Jews might want to come to America, even if they knew you want them to stay where they are. I don't advocate forcing any of the Jews in Israel to come to America, but I think it would be good of us to offer each of them a choice.
