Deja vu. We have this discussion every 6 months. Israel left Gaza and the rockets began which lead to the blockade. Stop the rockets, you eventually will not have a blockade.
Notice there isn’t a blockade around the West Bank (checkpoints aren’t blockades). There are tons of palestiniens that manage to live a decent life in Israel and are better off in the West Bank than Gaza. The main factor is the elected group hamas.
Of course if hamas loses power, Islamic jihad will be there to take its place.
