Ron Arad was the trade that was never made. After this there was a resuce attempts made on a captured IDF guy in which the prisoner, and a few others met their doom. The 2006 war was sparked by a Hizbollah border raid in which they captured two IDF men. Sadly, the men were badly wounded in the fight and ultimately died, although their remains were exchanged for Kuntar, a captured Lebanese guy. Now we have Shalit which is hanging fire for four years and counting. It is in Hamas interest to keep Shalit alive and healthy, since this issue is a loser for the Israeli government. For the Israeli government, a dead Shalit is far more desirable. If this happened they could exact one last payment by killing a few Palestinians and then everyone could move on, forgetting Shalit as quickly as possible. Sadly for the Israeli government, Shalit has proven to be more tenacious than expected, and Hamas more nurturing as well. Together, they are giving Bibi a difficult time. Bibi inherited the Shalit problem. If he passes it along to his successor, nobody will ever forget it. Bibi should solve the problem now. If this means emptying the Israeli prisons, then so be it. Call it a lesson learned, the hard way.
