Although the American side tries to present itself as holding the upper hand, in reality, Iran currently holds the advantage. This superiority is evident in three main areas: limiting negotiations to the nuclear file, choosing the location of the talks, and maintaining indirect communication.
Regarding limiting the negotiations strictly to nuclear issues, although the US has seemingly backed down, this should not lead to optimism or excitement. The Americans are known for deceit and broken promises, and they may raise unrelated issues once talks begin or during the process.
The indirect nature of the negotiations allows Iran to withdraw without significant cost—or at least with minimal cost—should the other side attempt to bring up unrelated topics such as Iran's defense capabilities or regional issues.
Trump’s false claims about the nature of the talks are also rooted in this strategy. He aims to apply psychological and media pressure on Iran to force direct negotiations, while in practice, the US has already agreed to the indirect format.
