Sigh.
One of the more frustrating things on FR is a the common assumption that if someone is concerned that Israel's security situation is continuing to deteriorate, it must be because they're besotted with love for Islam.
I don't know anyone around here, myself included, who would not prefer living in Israel to living in any of the surrounding states, or to any Islamic state is likely to exist within our lifetimes.
But as I noted in that post, I'm not speaking to the question of the relative moral or ethical qualities of either society, nor to questions of legitimacy based in pre-World War I history or in religious opinion - on either side.
The question is whether Israel is a source of security or a source of risk for the Jews living there.
My take on this is pretty simple: Israel is geographically a very compact country, three relatively small fission weapons would be sufficient to decimate its people and infrastructure.
There is a highly unstable Islamic state - Pakistan - already possessed of such weapons and largely under the control of an intelligence service with many high-ranking members supportive of the cause of radical Islam in the form of the Taliban and perhaps of Al Qaeda.
Such an intelligence service has the knowledge and financial depth to mount a sophisticated operation to get those weapons into Israel, emplaced, and detonated - and such an operation, properly conducted, could be very difficult to stop - there is a considerable chance of its success. (The successful attempts we are somewhat aware of to interdict terrorists have depended on the fact that they are non-state actors and have a difficult time flying under the operational and financial radar of Western intelligence services, this would be much less true of a professionally run state-sponsored effort - even if the was a rogue faction of the state undertaking it.).
Thus when considering mass casualty attacks, by far the most damaging attacks that can be mounted against the world's Jewish population would likely be mounted in Israel.
And there is very little that either Israel or the United States can do about this - both have only very limited political influence in Pakistan and neither has a practical non-diplomatic option for suppressing the ISI and its freelance minions - if they're willing to sacrifice Pakistan to the cause (and clearly some are fanatical enough to do so) there is virtually nothing we can do to stop them other than to attempt to discover and thwart such schemes.
And if Israel is the site of the second great modern Jewish Holocaust, arguments about the relative moral values of Israel and its neighbors, or about the historical rights and wrongs of Israel's establishment and the subsequent expansion of its borders, are going to be pretty meaningless.
