The recent Iran–US peace deal has been one of those moments people didn’t really expect to see in real life. After years of tension, proxy conflicts, sanctions, and repeated military escalations in the Middle East, things finally reached a point where both sides agreed to sit down and stop the fighting. The deal was signed as a 14-point memorandum of understanding, with the main goal of freezing the conflict and opening the door for a more permanent agreement later.
