Reminds me of a story I read shortly after 9/11 when plans for military operations against Afghanistan began.
The only problem with this article is it lacks context. Is this a bigger order than usual or is this something Israel does every 12-18 months anyway? A bit of research done there could be interesting.
If Kuwaiti rumors are true, then this could be because of a potential war with Hezbollah & Syria, not strictly Iran - http://www.haaretz.com/news/diplomacy-defense/report-israel-planning-to-attack-hezbollah-arms-depots-in-syria-1.310655
lots of stuff to digest in that Haaretz article. Sounds like things are tense along the Israel-Syrian border
