Former Hamas member and former Shin Bet informant Mosab Hassan Yousef: Israel's existence is not a negotiable and it does not depend on superpowers or the public opinion. And if they keep pushing Israel to the corner, they are the ones who are gonna suffer the most. Israel hasn't used everything that it has and Israel on a purpose did not expose the advanced weapons that it has for very important reason. We don't want the enemy to know what we are having and now at this point we're just playing around. So this is the clear message to those who think they can annihilate Israel.
