Three years after October 7, Middle East alliances and US influence reshaped

Al Jazeera's three-year assessment reports that Iran's regional network has been badly weakened, while a US-Iran war this year has disrupted the Strait of Hormuz and Houthi gains threaten Bab al-Mandeb. Analysts cited describe waning confidence in the US as a security guarantor, with Saudi Arabia, Turkey and Pakistan signing a mutual defence pact in August. The shift leaves Israel militarily dominant but diplomatically isolated, and shows the region realigning around new blocs, the kind of multi-power setting in which wider regional war remains a live risk.
