Iran and world powers will meet in Turkey and re-open talks about Iran's possible nuclear development programs. Nations like the United States, Russia, and France want to curb the growth of Iran's uranium enrichment program. The world powers believe it could lead to a nuclear development program. This program presents the threat of war in the Middle East, an occurrence many want to avoid at all costs. To prevent this outcome, the world powers have been imposing strict sanctions on Iran. They believe their sanctions may have been successful because Iran is willing to at least talk about it.
The two sides of this argument are quite distinct. The world powers do not want Iran to have a nuclear development program; the threat of war in the Middle East is too great. Iran, however, believes this type of program is their inalienable right. It is for this reason that previous peace talks have failed. Iran's recent willingness to enter into peace talks is encouraging to the world powers: Iran may be ready to compromise.
Logos is present in this article through the past actions of the world powers: they wanted to stop the progress of Iran's nuclear development program, so they imposed strict sanctions. Iran, however, makes a value claim by saying the program is their inalienable right. The peace talk, in itself, will be full of policy claims about what each side should do.
