The circumstances you reference are exactly why it seems so improbable to me.(see my post #40) So much is risked and there is nothing to gain - if this strategy was authorized by Hamas. I am, however, a bit uncertain of the relationship of Hamas and the other factions - splinter groups? - like Qassams Brigade, etc. Can you do a quick tutorial? Anyone?
