The article doesn't say when the latest refusenik joined, but it does mention that the group has grown rapidly and is now up to 462. That's not bad.
They CLAIM there are 462. In fact, these characters held a meeting a couple of months and only slightly more than 200 :) showed up. Either there are not 462, or some of them do not have the stones to show up in public. And that 462 or so number has not changed in months.
An extra 4000 reservists over and above those drafted volunteered for the last op.
Last I checked the list (a long while back) there were lots of multiple entries and lots of fake entries. Frauds, swindlers, your basic bottomfeeders. Of course you enjoy that collection.
Here's hoping that the Israeli govt does the sensible thing with the ones of them that actually are real: shoots them.
