The differences, say analysts here and in Washington may not be significant. North Korea already has nuclear warheads while Iran denies it plans to make them. Iran has launched satellites while North Korea claims to have done so but has not. North Korea has developed long-range missiles, including the one that failed last week, while Iran has focused on advanced versions of middle-range missiles capable of reaching Israel.
“Iran in most respects is a larger, more sophisticated country,” observes Greg Thielmann, formerly with the State Department and now senior fellow at the Arms Control Association in Washington. “They have a lot more resources. The Iranians have conducted a lot of missile tests. North Korean testing is much less frequent.”
