In a previous post I suggested that the reason for the terror groups to stop Qassams is not to allow Israel to wiggle out of its dire diplomatic situation by allowing it to go on the attack in Gaza which would cause the PA to drop its pro-peace posture. But Hamas has a good alternative to continue its "resistance", and this is planting mines in the "buffer zone' (of 300 meters) along the border with Israel. The IDF tends to attack by entering the zone, and then suffers casualties. Israel has a hard time justifying such zone and such attacks. While the UN and the rest of the world view Gaza as still "legally occupied" territory, Israel claims that its occupation has ended. If so, Israel cannot claim the right to impose a no-man's land in Gaza, and has to concede the right of Gazan farmers to work their land. Israel's questionable legal position makes it the aggressor in the buffer zone dispute and makes Hamas the hero. Why use Qassams who you can become a hero?
