A reader writes as below. I am not convinced but she or he makes a credible argument:
"Iran is nowhere near completing a nuke. Threats that they are getting close is just a Likudnik talking point.
The real issue here is that Hamas wants to influence the Israeli election to keep Bibi in power. They are extremists, and the only thing they hate more than extreme right-wing Israelis are moderate/left-wing Israelis who might restart the peace process. Hamas (and Bibi) are enemies of peace, and share the objective of keeping the conflict going, and keeping each other in power.
Anyone other than Bibi winning the Israeli election would put Hamas' power at grave risk of being replaced by more moderate folks, as such, they are determined to enrage the Israeli population into re-electing Bibi and taking the risk of peace off the table.
The only question is: Will Israelis fall for it?"
