The Israelis should continue the blockade of Gaza. The Palestinians have been given numerous overtures and still have the option for a peaceful solution if they want, but every time they choose war and terror. They do not want peace; rather, their goal and desire is to drive the Israelis into the sea and wipe them off the map.
As for the outrage expressed by the Europeans, etc., it is quite obvious they are in a “Chamberlain mode,” and should think back to what that cost them (not counting Jews). That is what the Jihadists want: The World Trade Towers. The subway bombing in London. Suicide attacks all over the world on strictly civilian targets. Israel should deny the Jihadists their bomb-making materials by any means and not listen to the Chamberlains among us.
