That guy might be an asshole, but the situation is a little more complex. 

In 1948 tens of thousands of Jews were expelled from east Jerusalem, where they had lived for generations. Jerusalem had been majority Jewish for decades at that point. The empty houses were then given to Arabs by the kingdom of Jordan. 

When Israel took all of Jerusalem, the people who had lost their homes in 1948 tried to get them back. However they were occupied by Palestinian Arabs then. Decades of lawsuits followed. Some gave up their claims, some came to an arrangement like paying rent. 

Taking a house back that was stolen by the current inhabitants, isn’t exactly stealing.
