Ian Bremmer shares his insights on global politics this week on World In :60.

How will Iran respond to the attack on their consulate in Syria?

An Israeli strike that killed the Islamic Revolutionary Guard Corps leader of Iran in Syria. So on the one hand, Iranian citizen, high-level military official. On the other hand, not in Iran itself, in Syria supporting proxy attacks. Clearly the Iranians have been willing to push hard using the leverage they have in the so-called acts of resistance to engage in strikes against civilian shipping, against Western military capabilities, and against Israel.

The Israelis are showing that they will attack wherever they think fit against them, but Iran has been reluctant to allow this to potentially lead to escalation in a direct war against Iran, which is why it's hard to imagine the Iranians engaging in direct strikes against Israel itself. Ballistic missile strikes from Iran into Israel. So in other words, if you're going to hit Israel, you try to use proxies or you try to hit Israelis outside of Israel itself. Israeli diplomatic facilities, for example, that's where I think you're more likely to see escalation. Escalation seems almost certain from the Iranians, but containing it also is something the Americans and Israel are trying very, very hard to do and that continues to be the case like when we saw the American servicemen killed in Jordan a couple months ago.
