All Palestine their home: a prophecy of Abdu’l-Baha?

In the older editions of Some Answered Questions (pp 65-66 in the 1985 edition), Abdu’l-Baha says,

In the same way, Israel, scattered all over the world, was not reassembled in the Holy Land in the Christian cycle; but in the beginning of the cycle of Baha’u’llah this divine promise, as is clearly stated in all the Books of the Prophets, has begun to be manifest.

You can see that from all the parts of the world tribes of Jews are coming to the Holy Land; they live in villages and lands which they make their own, and day by day they are increasing to such an extent that all Palestine will become their home.

The question was asked, is this a fulfilled prophecy of the Master, or is it yet to be fulfilled?
