Ian Bremmer's Quick Take: Hi, everybody. Ian Bremmer here back in New York City and a Quick Take to kick off your week.

We are talking yet again about the war in the Middle East continuing to escalate. Certainly not the news that anybody wants to hear right now. Israel with tanks now rolling into central Rafah.

This is the warning that the Americans had given the Israelis for over a month now, not to invade that area. The Prime Minister and others on the War Cabinet have said that they will persist until Hamas is destroyed, and that critically includes Rafah. This comes after roughly 1 million Palestinians have fled the area, having been warned by the Israelis that they're going to attack it. Over the past couple of weeks, of course, it's not clear that they have anywhere safe to go. Certainly, nowhere with infrastructure or with adequate humanitarian support. Comes after airstrikes by Israel hit a camp for people displaced from Rafah that killed over 45, mostly women and children, as well as two Hamas officials. Prime Minister Netanyahu referred to that as a tragic error. They've been a lot of those over the course of the past months. The United States, as I said, strongly opposing the invasion and calling it a red line, sort of. I mean, that red line also came with all sorts of caveats that the United States wanted to ensure that aid was going to be able to get in.
