Netanyahu let Sinwar out of prison in 2011. How strange that Sinwar attacked Israel the day before Bidi's career ending corruption trial was to begin.
If you ask me, Sinwar's death should serve as a warning to all aspiring Arab elites that see an alliance with Israel as a path to power. Blackmailed parties often come to see their blackmailers as allies when rewards are involved. And when their new allies betray them, the best they can do is lob a stick before they die.
