Tell that to the Palestinians families whose homes they owned for generations were stolen by Israel and their children are now murdered in the most horrible ways.
I'll tell them that opening the war on Israel and the Jews on 1948 was the wrong move and they unfortunately paid a hefty price. It was a choice, done at a community level: many Arabs chose to accept Israel and not attack it in 1948 and are now Israeli-Arabs (about 23% of the population). Nothing was stolen from them and they are amongst the most prosperous Arabs in the Middle East.
