I guess that depends on what the meaning of is not is…
W reacted to the report that Iran halted its nuclear weapons program several years ago by arguing that the new data is yet more proof that we are in danger.
So, I view this report as a warning signal that they had the program, they halted the program. And the reason why it’s a warning signal is that they could restart it.
If only they hadn’t halted the program. We’d be safe.
Bigger picture. About half of Iran’s population (a population that until recently was fairly pro-American) is under 20 years old. Our sanctions are making it tougher for many of those young people to find work. Angry, broke and young and in that region. Now that’s a warning signal.
