The renewed aggression between US and Iran is unsurprising — it highlights the ongoing tension and lack of trust.
Both countries need a permanent peaceful settlement for mutual benefit — failure to achieve this could lead to further instability.
A more probable desdevelopment: Increased sanctions or military tensions that may disrupt regional stability.
This is sadly unsurprising. The only real question is when it will hit home to both countries, especially Iran, that it is in their interests to arrange for a more permanent peaceful settlement.
