Israel' delay of delivery of the Herons is probably an anger factor, especially for those who supported signing this deal and for those who actually signed it. It is a bureaucratic nuisance more than anything. But I do not think this really is the reason for all this mess. Having said these, there is really no explanation of why the Herons got delayed. Israeli Defence Industries are such efficient institutions, it is impossible that they did not finish the job on the day they promised they woud, israelis probably wanted to deliver the stuff late on purpose, I do nto believe they did not finish the job. Why ? Anyone's guess...
