I've been seeing posts by people here supporting Isreal in this matter just because Palestine is a Muslim country, forgetting that Israelis are not Christians.
Anyways, here are some screenshots detailing the origins of this matter.
Read and judge for yourself. You can also do some research into it.
I won't support Isreal just because I'm a Christian. It is morally wrong.

There's a short film on Netflix "The Present" showing the day to day struggles of people living in the West Bank.
It is an eye opener to seeing how people live there.

Half truths.
Palestine was never a country. Arab invaders settled in Jerusalem and other towns jews had been occupying for centuries. In 70ce, Romans destroyed Jewish nation and jews were dispersed. Arabs in surrounding nations invaded and settled in Palestine which is just part of cannan land . Other Jewish settlements in other sides of Palestine were now occupied by Jordan, parts of Syria and Lebanon. This was possible because most of these lands occupied 10 tribes of Israel were destroyed by Assyria army. But for the sake of coming of Jesus, kingdom of judah was preserved. Even when Babylon destroyed kingdom of judah in 607 bce, king of Persia ordered jews to rebuilt Jerusalem and second temple.
Jews suffered in the hand of Greek and Rome again. Jerusalem, the capital was destroyed in 70Ce.
Romans administered Palestine for centuries. Later ottoman administered Palestine and muslims built mosques at centre of mount temple but jews were still in palestine doing business amassing wealth and acquiring properties. These properties were documented by ottoman empire for tax purposes.

British later took control of Palestine and jews were doing fine.
After holocaust many Jews returned to their ancestral land. Arabs sold lands for them.
1948 war. Jews lost sheikh Jarrah ( cause of presence crisis) . During ottoman empire, Jews had acquired many properties in Jerusalem including sheikh Jarrah.

After the war, Jordan controlled sheik Jarrah and Jews were expelled from their homes.

1967 war. After 1967 war, Jordan lost west bank including Jerusalem, of course sheikh Jarrah. Arabs were not expelled but since they time Jews have been getting their properties back.
