Both sides were/are wrong to much differing degrees. Hamas shouldn’t have sent missiles into Israel. Maybe they felt hopeless and thought it would break the log-jam, maybe they just wanted to kill Israelis, don’t think we’ll ever know. Israel has a right to retaliate, but it’s gone way, way past retaliation to Annihilation.
The Palestinians will have a long memory and won’t be snuffed out by continuing to attack. They will be even more bitter than they were before and continue to fight for the home they were given in Balfour Declaration in 1917. The world needs to back the Palestinians right to independence.
