Anyone who thinks that because a bomb has fins it is a "smart" weapon should learn to read and maybe what a few World War II movies. All bombs dropped from aircraft have fins. The MK-82 is a cheap bomb but it is not a smart bomb. It serves as a basis for the GBU-12 laser guided bomb, which is a smart bomb. I assume that the UN personnel can tell the difference. The article makes it unclear as to whether the bomb exploded or did not. How could they disarm the "remains" of a bomb. Either it was intact and dangerous, or they found it exploded--and no longer dangerous. Assuming that the bomb wasn't set in place by UN personnel, or Hamas and other terrorists, of reporters, there are _many_ explanations for how the bomb (or remains of a bomb) got there. Only one requires that the Israelis lied. That so many people are willing, no WANTING, to use this as proof of Israeli culpability is merely another sign of the virulent racism inherent in Palestinism.
