Geneva or elsewhere in Europe: US, Iran near deal but where will the peace treaty be signed?

The United States (US) and Iran are hopeful of a peace treaty, and have said that the deal is "closer than ever", hinting that the over three-month-long conflict in the Middle East is nearing its end. The proposed deal, which is being described as historic, will ensure "long-term peace" in the Gulf that was ravaged by the Iran war.
