I somehow missed it until now, but ACA’s Peter Crail had this very “clearly written piece”:http://www.worldpoliticsreview.com/article.aspx?id=3386 on nuclear safeguards in Iran online a few weeks ago:
bq. In the months ahead, the United States and its allies may confront a choice. Do we want to get Iran to suspend its known nuclear activities, or do we want to achieve the transparency needed to detect any unknown activities? Both are important goals in their own right, but it may be increasingly important to shift our focus to the latter.
I guess the answer to that question depends on what the U.S. brings to the table. Assuming there even is a table.
