Hamas digging out explosion victims - with Caterpillar equipment

Yesterday, an explosion in a Hamas bunker (or possibly a kidnapping tunnel) killed 5 terrorists and a rescue worker. 

Hamas is still digging out the bodies, as this photo from Felesteen shows.

Yes, that is Caterpillar equipment that Hamas is using.

Should we call to divest from Caterpillar because a terror organization uses its equipment (and in all likelihood, used it to help build the tunnels to begin with)?

It would confuse the hell out of the hypocritical Israel-haters.
