Credit Suisse has a long history. http://en.wikipedia.org/wiki/Credit_Suisse#Criticisms They should have been hit harder, sooner. However, I suspect that they're being investigated now because of their history of playing the harlot with Iran: "Credit Suisse settled on charges that it violated sanctions regulating financial transactions with Iran. The charges included "stripping", the practice of removing the identity and origin of funds used in transactions. Credit Suisse employees stripped the identities of Iranian banks enabling funds to be transferred to the Atomic Energy Organization of Iran and the Aerospace Industries Organization, entities respectively involved in the production of nuclear weapons and long range missiles. Credit Suisse advised Iranian banks such as Bank Melli and Bank Saderat on methods to hide their identities and send more than a billion dollars through New York banks."

If the message is at all significant then it's brevity would suggest shared knowledge between the sender and receiver (duh, I know). The most common and practical example of this would be an encrypted dictionary encoding. As for the number of words that could be referenced in this message, if they used a smaller shared dictionary (maybe 100 words) of pre-established nouns and directive-type words then this message of "93 882 naimina 74 14 35 74" could easily be message approaching 10 significant words. So there's plenty of room for a significant move-here/do-this type directive but there's not any room for detailed plans. It's also possibly an encrypted internet address where agents can go to download public, stenographic photos that contain the larger details and information that they need (or something of the sort).

I think sanctions may be "doomed" but I also think they MUST succeed because the alternatives will be messy. I'm mostly writing this because I don't think a good understanding of Israel's motives and POV considerations were expressed in your post and I think that of all the issues in your post that this is the most critical to understanding the status of this situation.

Ahmadinejad has expressed himself in ways that suggest a mind capable of using nukes on Israel without regard for MAD. How would Israel and other states retaliate? Nuke all of Iran? No. And so the act of destroying choice parts of Israel & her population via nuclear weapons is likely to be seen as beneficial for many of the extreme Aarab nations. Will Ahmadinejad do it? No one has the ability to judge his intentions but I'd be more than concerned if I were Israel. I think preemptively striking their refinement facilities would be prudent if Iran is not being completely transparent if their refinement. It would cause comparably minor casualties but would unfortunately necessitate the declaration of a new war. However, it is more favorable for Israel to be at war than to find out they are at war after Iran's first nuclear detonation.

Mostly, I think Israel's cease and desist declaration is designed to both deter Iran and to incentivize the UN into other solutions that halt Iran's nuclear enrichment. Israel will be very hesitant to attack Iran without a majority of UN support and will only follow through with an attack if they feel it is absolutely necessary. Remember though that they see it as a strictly defensive move and that they gain nothing from provoking yet another Arab nation. The likelihood of a war with Iran, including heavy missile retaliation, ground fighting, and increased "terrorist" actions, is not unknown to Israel. They know they'll have to pay for any bombing they do and will only pursue a bombing if they feel even more threatened by the possibility of nuclear weapons in the possession of a hateful enemy. They know what a preemptive attack would mean for their region better than we do. However, like us, they would prefer a bloody war over their potential inhalation or over the possibility of a devastating nuclear war. Even the US went to war when they thought one of their so-so enemies had WMD (not a good decision). Now considering Iran's expressed intentions towards Israel and their proximity to one another, I think the threat posed by the Iranian nuclear program justifies a targeted attack by Israel if sanctions fail and Israel still thinks that the program is likely to eventually yield nuclear weapons.

It wouldn't surprise me. In contrast to some of the posts saying it's because they're faithless, fearful, or foolish, here's some fair possibilities as to why they may wish to prolong life:
1) Those who believe they were given life SHOULD value it more than those who believe we are products of randomness.
2) Similarly, they likely believe this life has eternal significance rather than temporal only.
3) They believe they must answer for how they spent their life and may feel shame & regret at all their shortcomings (no matter how minor or major). They tend to want a second chance (Like in Schindler's list "I could've got more...")
4) For some, it might even be more like pre-wedding jitters.

I don't pretend to know people's motivations. They could all be faithless, fearful, and confused. But I really don't think it's intelligent to attempt to draw out definite conclusions based on the behavior of such a small subset of humans, especially where it is so dependent on their honesty. For example, it wouldn't surprise me if more than 50% of the people who said they prayed regularly didn't pray at all.
