The government's changed policy was to allow all items into Gaza (other than those with military uses), rather than allowing only the absolute bear necessities. So why tell us about the number of trucks? indeed, it was estimated that the "siege" caused a ten-fold reduction in the number of trucks going into Gaza. This means that the government new policy will be fulfilled when roughly 10 times more trucks go in. A rise of 50% (from 100 to 150) is a drop in the bucket, but it sure looks nicer.
