Iran has been using Hamas for its anti-Israel agenda. Iran is Shia and Hamas is Sunni, so there is this divide between them.
Hamas suffered as a result of the last war. A lot of the infrastructure was destroyed. Iran has been arming them and egging them on. Occasionally Israel intercepts arms shipments from Iran to Hamas.
Hamas has backed off recently because it doesn't want to restart what it just went through, and Iran disagrees with that. Iran wants Hamas to keep on attacking Israel, so there is a bit of a drift that way.
This kind of drift obviously doesn't give me any sense of satisfaction with Iran, quite the opposite. It says something about Iran. If you read the Hamas charter you can't imagine anything more anti-Jewish and anti-Israeli but it's not good enough for Iran. They want more. So I think that gives you an idea of the extent of the problem we're facing with Iran.
