Negotiations between Germany, France, the UK, and Iran are scheduled for Friday in Istanbul to discuss Iran's nuclear program. The talks aim to address concerns about the program's potential for weapons development and to ensure compliance with international agreements. For Iran, these negotiations are critical as they could lead to the lifting of economic sanctions and reintegration into the global economy. However, significant disagreements remain between the parties, particularly regarding the scope and timeline of Iran's nuclear activities and the verification mechanisms in place. The outcome of these negotiations will have significant implications for regional stability and international security.
