Wouldn’t it be nice:

The launch of the CPI brings to the fore something often forgotten when discussing Iran: the Islamic Republic has suppressed political parties so completely that an entire generation of Iranians has never experienced genuine political pluralism.

If the regime collapses, the absence of organized political institutions could leave a vacuum. Groups like CPI are attempting to prepare for that possibility. …

“The Conservative Party of Iran stands firmly upon the enduring pillars of Iran’s historical and political truth,” the declaration states. “Its national identity, its sovereignty, and the continuity of Iran’s native polity – the monarchical institution.” …

Amiri argues that the resurgence of monarchist sentiment in recent years has been visible across Iranian society. …

Still, Amiri emphasized that the ultimate decision must come from the Iranian people.

“The legitimate determination of Iran’s political system must come through a free national referendum held under democratic conditions,” he said. “We do not prejudge the sovereign will of the people.”

Even if the outcome were to differ from current expectations, he added, the party would adapt. …

[The CPI’s] draft constitution outlines a political organization that resembles parties operating in established democracies. …

“To restore Iran’s economy we would begin with disciplined monetary policy aimed at stabilizing the rial,” he said.

Much more at the link.

They’ve certainly had a while to think about all of this.
