Saudi Crown Prince spoke with Kuwait's Emir about criticising Iranian strikes on Wednesday. Pakistani PM contacted him, calling Houthi strikes in the Red Sea 'unacceptable.'. In Washington, discussions revolve around a planned US-Saudi nuclear agreement. The pact is tied to normal ties with Israel under conditions set by former US President Donald Trump. Iranian officials are examining how the talks might alter the wider regional order. Observers flag that the pair of tracks of security and diplomacy has put Saudi Arabia at the centre of talks across the Gulf. Quiet channels between Saudi and US envoys have continued through recent weeks, even as attacks and replies have dominated headlines. One western diplomat said the civil nuclear file was now closely linked to the Israel file. Around Saudi decision makers, the priority has been on keeping the kingdom safe, rather than public messaging. Meanwhile, Tehran is reportedly counting the costs if the nuclear arrangement pushes ahead, with an Iranian veteran warning of fresh pressure across the wider Middle East.
