It is Israel, but God promised them land from the River (Euphrates) to the Sea (Mediterranean). When the Palestinians shout "from the river to the sea," they are calling for the annihilations of Israel.

...and then they worshipped idols, disobeyed the Commandments, and got themselves rekt. Again and again, until they were instructed to not "rise over the wall" and remain loyal to their cities of residence.
Under Simon bar Kokhba, Judah attempted to genocide all their neighbours until Rome intervened with a professional army. One of Bar Kokhba's officers repented, and under the latinised name "Flavius Josephus" wrote a book that sounds remarkably like current events.
I wonder why they would want to annihilate Israel. Perhaps it is because the Jews owned 7% of the land but claimed almost the whole country, and are now ethnically cleansing them.
I guess if they were good Christians they would follow the example of Christ and just let the Jews murder them.
Also, "Israel" the nation-state has nothing to do with the "Israel" of the Bible.
