Israeli Bulldozers

Below is a photograph from CNN's Web site today. The story was called "Palestinian PM pleads for Gaza calm." I have heard about the Israel Defense Forces using armored bulldozers but have not seen many pictures of them. This is very strange.

CNN's caption said "An Israeli army bulldozer razes Palestinian greenhouses Thursday as part of the military operation in northern Gaza."

I am utterly baffled why the search for a kidnapped soldier necessitates the destruction of a greenhouse. Sometimes I feel like I'm from another planet, and I just can't understand why people do things like this.
