Reza Pahlavi, the exiled son of Iran's last monarch, has issued a stark warning against the framework peace agreement scheduled for signature between Iranian and American representatives this Friday.

He characterized the potential accord as a "strategically serious error" and argued that the Iranian people would not benefit from the proposed terms.

The intervention from the Pahlavi heir adds a layer of internal political complexity to the diplomatic push.

While the United States and Iran are moving toward a formal framework, the opposition from a prominent figure within Iran's historical elite underscores the fragile domestic consensus required to sustain such a deal.

The upcoming signing represents a significant escalation in engagement, but it also exposes the regime to criticism from both internal hardliners and the exiled opposition.

This development follows a period of intense diplomatic maneuvering.
