On Friday, Turkiye, Saudi Arabia and Pakistan signed a mutual defence pact, building on a similar agreement between Riyadh and Islamabad last year. Experts have speculated that the deal may mark the beginning of a wider regional alliance that sits between Israel and Iran, wary of both. Saudi Arabia, and Turkiye to a lesser extent, have long considered the US a key security partner. Saudi Arabia, for its part, has responded with strikes on Iranian-backed groups in Iraq. Are Saudi Arabia, Turkiye and Pakistan willing to do that for each other?
