The reports mention what is happening in Gaza, the shelling, the ground invasion, the civilian casulaties, the humanitarian crisis (no water / electricity / no food etc.). I think one problem in this war is that there is a lot of propaganda going around, and there is not enough reliable impartial information. So just because the Hamas is reporting that Israel bombed a hospital (as an example), that the media will immediately pick up on that. For example, bombing a hospital sounds bad, but what if the hospital was acticely used by Hamas terrorists for ammunition storage, and even fighting from there? Is is now OK for Israel to attack the hospital? I don't think the media should immediately pick that up, because that information is not verified, and could as well be propaganda.
In my opinion, one of the reasons the palestinian people are suffering so much is because of Hamas, and how they use civilian infrastructure and hide in the population as their strategy. There is no way for Isreael to "win" without massive civilian casualties. And we should also not forget that Hamas is not innocent, they are not "just defending" their country. They started a war, which they are now loosing. You cannot attack another nation state, and then expect them not to do anything about it?
Also keep in mind that Hamas is recognized as a terrorist organization in Germany, while Israel and Germany maintain good political relations. It makes sense that Germany is more supportive of Israel.
