Hamas’ shock terrorist attacks cut deep into Israel's territory. That psychological trauma compounds the shock for millions of Israelis that their world-class intelligence and security forces completely missed the warning signs. That’s why comparisons with the 9/11 attacks on the US are the right analogy – Israel’s weakness was, in part, a failure of imagination, Ian Bremmer explains on GZERO World.

Now to Gaza. Hamas has launched a suicidal war, and Palestinians will pay dearly for it. But why did Hamas move now? In part because of their deteriorating position: blockaded by Israel and Egypt, the economy in Gaza was terrible and getting worse. Meanwhile, the geopolitics were leaving the Palestinians behind. Israel is in its strongest geopolitical position in decades and was on the verge of signing a historic peace deal with Saudi Arabia. The severity of Israel’s expected response – a ground invasion that will result in thousands of Palestinian deaths – makes that politically untenable for the Saudis now.
