Whether or not Hamas is a terrorist and/or humanitarian organization is a matter of perspective, don't you think?
I'm sure the Palestinians consider the missiles and mortars that are coming from Israel as inflicting terror. Therefore, the Palestinians consider the Israelis to be terrorists.
The founders of the USA were considered terrorists by England.
You see, trying to pass judgment by labeling one party of a conflict as terrorist, doesn't get you anywhere. You should look a little deeper. The world is not black/white, good/bad.
