Israel isn't under attack, but it feels like it right now. It's in the midst of a five-day emergency drill called "Turning Point Three", where schools, hospitals etc. run through what they'd do if under a multiple missile attack. During my visit in March, I was struck by the number of Israelis who feel that it's inevitable that Iran will get the bomb - and the question is how many will stick around and wait for the Ayatollahs to try another holocaust. This squared with a recent opinion poll, which suggested a quarter would consider emigration if Iran got the bomb. And this morning's sobering assessment about Iran's capabilities will do nothing to undermine the concern in Israel.
P.S. For a superb primer on Iran's nuclear timeline, here's a podcast discussion from the AEI.
