I've never understood the purpose in placing unarmed "observers" along a volatile border such as the Golan Heights between Israel and Lebanon.
Back in 1993 I stood on an east-west road running the length of those heights. Behind me on a ridge stood an Israeli electronics observation post. Our guide had warned us not to photograph it because the Israelis had been known to seize photographic equipment from those that did so and retain the owners for questioning.
Overhead flew an F-16. While we stood there, two immense flat-bed trailers passed by, hauling M-109 self-propelled artillery pieces.
This was an impressive display of vigilance and security along a blood-stained border.
To the north, at the bottom of a small valley, lay a small camp of UN observers, armed with small arms and light-transport and utility vehicles.
I thought then that the only thing that small group of powerless men could accomplish was to provide a source of considerable mirth to the Israelis and the terrorists to the north of that camp.
