saudi arabia-israel ties

US President Joe Biden didn't get much from his recent trip to Saudi Arabia — other than some symbolic progress on Saudi ties with Israel. Indeed, Biden's plane flew directly to the country from Israel, and now Israeli airlines will be allowed to overfly Saudi airspace. But is this really a big deal? "I would describe it as [...] giving crumbs to Biden," Bernard Haykel, a Princeton University professor and expert on Saudi Arabia, tells Ian Bremmer on GZERO World.
