Without going into ever more detail and, as reflected in history, a tendency towards increasing animosity.
I thought it would only be a matter of time before somebody would come up with "Israel did it" and I wasn't to be disappointed. I'm gratified by your view though, given what seems the overwhelming evidence to support a Lebanese government cock-up, resulting in an almost inevitable disaster and a total lack of anything at all that points to Israeli involvement (not least a credible motive), you don't believe that to be the case. I understand - options reserved of course.
Whilst I'm sure (I take your word for it) some forums are alight with the idea of Israeli involvement, there being absolutely no reason to suspect one or any evidence at all I think points to why it hasn't been discussed more widely in the press/on TV. Why would it be? That surely explains the dearth, rather than fear of antisemitism accusations. In fact, if you have a look you will find the idea was actually pushed around by a few tomes. One of which, from 2 days ago, talks of there being 5000 Social Media posts about an Israeli strike. A lot of Social Media/Forum folk do love their conspiracy theories. You can get one on just about anything.
In this thread you've introduced, or made passing reference to, elements which have no bearing at all on what happened in Beirut last Tuesday. I'll leave them where they are I think, rather than go off on an unrelated tangent.
Today, it seems there are widespread protests on the streets of Beirut. Many have been heard calling for the government to be hanged. They're obviously not buying the Israeli scapegoat line. The chiefs of Beirut port and customs have been arrested. Ready to be lined up I imagine, despite the fact reports say that over 6 years they repeatedly warned the government about the danger and potential consequences of keeping the seized cargo. More shots at scapegoats I suspect.
The Guardian and Al Jazeera are reporting that a port employee - Yusuf Shehadi - saw 30 to 40 nylon bags full of seized fireworks (from 10 years ago) stored in the same warehouse as the ammonium nitrate. You couldn't make this up.
