And Israel was not a Nation after AD125 when the Romans destroyed it. The land was ruled by Muslim Rulers Christians briefly during the Crusades, by the Ottoman Turks and then the British afterwards. Palestinian Muslims, Christians and Jews all got along as neighbors until Jews from Europe, who were never a part of Israel came and took Arabs from their ancestral homes at rifle point. Even to this very day, Palestinian Jews protest the treatment of their Muslim Brothers by the European Israelis.
Your history is wrong.
Israel was a nation:
From the 12th Century BC to 586 BC
From 140 BC to 37 BC
From 1948 to the present.
Israeli Palestinian Arabs fought against Palestinians in Gaza.
But why cares? The point is that Israel IS a sovereign nation and Palestine HAS NEVER BEEN a sovereign nation.
Nobody (EVEN ISRAEL) is opposed to the Palestinians creating a nation, even in Gaza. Israel even suggested this, and tried several times to help Palestine become a nation.
The problem is Palestinians outside of Israeli Atabs (Israeli Palestinians) do not want to be a nation alongside Israel. They advocate genocide and destroying the nation of Israel.
EVERY TIME Israel has defended itself, then called for peace, suggesting a two nation solution, the Palestinian Arabs and Arabs who are not Israeli citizens refuse and call for the destruction of Israel. Everytime it happens this way.
Israel defeated Gaza, parts of Egypt, Jordan and Seria (and Iraq and Lebanon support) when those nations attacked Israel.
Did Israel retain the land they conquered?
No. They gave it back for a permanent peace between their neighboring peoples.
In fact, the anti-Israel Palestinians who left Israel and fought to destroy Israel were encouraged to do so by the Arab nations. They were to return after Israel had been defeated. But Israel won. The Palestinians who remained in Israel were not penalized. They remained Israeli citizens. Those who left and joined the attack on Israel were not allowed back.
The Jerusalem Temple is Israel's most holy site. Did they keep it? No. They gave it to the Muslims for peace in return.
Israel has more claim to the entirety of Judea than does the Palestinians. Israel was the first nation to hold that land. Israel existed in that area as a nation 3 times in history. Israel is currently the sovereign nation of that land. The Palestinians were never a nation in the land.
I have to side with Israel on this one. Just because a people wants to destroy a nation and take their land does not give them that right. The best solution is Palestine becoming a nation AND Israel remaining a nation. The problem is only Israel is interested in peace.
