Uhm Corrik, Iran had to get rid of 2/3rds of their centrifuges and 97% of it's enriched Uranium. Which so far they have complied with completely. Also it's not timed. There are certain measures that expire, but not having nuclear weapons isn't one of those.
Also the agreements were for 2 uranium enrichment plants and a 3rd one which was to come online.
The main concern was with Iran being so mountainous that there can be undisclosed plants they are unaware of. Iran does not have to have plants not disclosed checked. Only upon disclosure.
It also is expected to just temporarily pause their production. And that Iran can go back to their status quo beforehand afterwards if they wish once the requirements run out.
The fear of course is that Iran will just use that as leverage to sweeten their deal. It gives them a position of leverage to deal from.
The Iran plan for many was considered flawed from the start but also considered to be the best way to stop Iran from completing the production of a bomb in the near term.
That it also had to come with the agreement supposedly to leave Iran's ally, Syria, relatively unscatched also despite their atrocities is another story.
I'm not sure why you linked that article as it doesn't contradict anything I said or support anything your said. The restrictions on weapons COULD be lifted in x number of years. They don't automatically expire. ---
Conformity and rebellion...both ways are simple-minded--they are only for people who cannot cope with contradiction and ambiguity.
