After Israel attacked Iran few days ago, it didn't take long before Iranian Foreign Minister Abbas Araghchi announced his willingness to discuss the nuclear deal aimed at preventing Iran from acquiring nuclear weapons. The reason for this is most likely the Jewish state's military superiority compared to Khamenei’s forces.
So far, Western countries have not, at least publicly, responded to the Iranians' announcement, instead choosing to watch from the sidelines as an uneven struggle unfolds, in which Israel demonstrates that it is militarily and technologically vastly more capable than Iran. This is the case even though Iran has managed to launch some missiles into Israel.
For the world at large—and especially for the Iranian people—it would likely be best if Iran’s Islamist regime were to collapse as a result of the war and be replaced by a religiously neutral government that would free its citizens from the religious terrorism imposed by the current regime. However, this would require a sufficiently strong force to emerge from within Iran, one capable of channeling public dissatisfaction into a revolution.
Another possibility for regime change could be the use of force by Israel or Western nations. However, I strongly doubt that anyone has the will to undertake such an operation, even though, for example, many Iranian refugees in Finland (an example and another) would undoubtedly wish for it.
It remains to be seen what consequences this ongoing and likely very short-lived war will have for the Iranian regime. Will it manage to maintain its position even in defeat, or will the Iranian people finally gain their freedom?
