If you were alive in 1948 to witness the beginning of Palestinian refugees,then your memory is probably about as good as Joe Bidens.
During the 1948 Palestine War, some
700,000 [fn 1] Palestinian Arabs or 85% of the Palestinian Arab population of territories that became Israel fled or were expelled from their homes. Some 30,000 to 50,000 [citation needed] were alive by 2012.

The descendents of these refugees from the first war is what you are talking about in other countries but the creation of Israel started it all.There were no Palestinian refugees before1948.
And more are being made every year as the Israeli government expands taking more Palestinian homes and raising them to the ground to make room for more Jews.
Jerusalem — Israel plans to build thousands of new homes in settlements in the Israeli-occupied West Bank in response to a fatal
shooting attack by Palestinian gunmen, a senior cabinet minister said. At a time of growing tension over the course of
Israel's war on Hamas in the Gaza Strip, Secretary of State Antony Blinken told reporters Friday that the Biden administration was disappointed by the announcement of new homes in the settlements, which he called "inconsistent with international law."
You have shown you are not capable of excepting the truth so you will call this history lesson a lie even though it is history.
