The feeling I got during the last months here when there are articles about this war is, that there are either many Israelis here flagging anything that makes Israel look bad, or many Americans, who somehow feel allegiance to Israel and think that this ever was about a good cause.
On the other hand of course there are also those that jump on any claim that makes Israel look bad. Claims of which there are many. Of which far too many have become pretty evident. Which far too many people do not want to be true and will ignore.
So what can one do? I guess keep an open mind and give claims a couple of days to be proven or disproven. Only then judge.
