I agree with you that PR is unusually important in this war. For comparison, the Nazis exploited civilian casualties (in occupied territories) of allied bombing in their propaganda. But that didn't have much effect in the scheme of things. In this conflict you see it has an effect on arms deliveries, etc, though not as substantial as Iran might have hoped.
But even is preventing bad UN reports is a covert war goal, bombing UN facilities is predictably counterproductive - it draws more attention than the reports themselves. So I'm skeptical that the IDF would bother spending the (reconnaissance) resources.

Sheltering Hezbollah or giving intel to Hezbollah are not that different. Both completely justify force and collateral damage, they asked nicely in 2006.
The reason I shifted my hypothesis is that they are hitting observation towers in combination with what happened in 2006.

The Unifill website says they mainly attacked their camera's. That suggests another possible motive, to prevent Unifill from sharing or leaking intel about IDF troop movements.
> UNIFIL also came under criticism during the 2006 Lebanon War for broadcasting detailed reports of Israeli troop movements, numbers, and positions on their website which "could have exposed Israeli soldiers to grave danger", while making no such reports about Hezbollah.
I find that somewhat plausible.

The IDF rarely comments on things, so that's really not evidence for your hypothesis that they attacked the UN deliberately to chase them away. My default assumption is that they're doing what say the war goal is, or at least trying to: get rid of Hezbollah. There's just no evidence showing otherwise here, yet.

Where things really get confusing is that nostr users are identified by pubkey, fediverse users by URL. When there's multiple bridges you get an infinite number of permutations, e.g. bridge1.com/npubabc, bridge2.com/npubabc are the same nostr user, and each fediverse user has one npub per bridge. And all can follow and interact:-)

Mostr is a piece of software that bridges between ActivityPub (e.g. Mastodon) and Nostr.
There's a public instance at mostr . pub, but it tends to get blocked by Mastodon admins. I run a private instance on my own domain too, but only my own replies on Nostr can cross that bridge.

There are multiple meanings of "deliberate". All this says is that they hit the building intentionally, that they aimed at it and it wasn't a stray. The relevant question is why they did that. To bully the UN or because Hezbollah was handing out there and the UN didn't bother sending them away? Remember that for more than a decade now the UN has allowed Hezbollah to operate there.

2024-10-10 20:57:31

- reply

I agree there can be all sorts of reasons for the attack, but I was responding to the claim / suggestion that it was a deliberate attack on the UN by Israel. That's not a reasonable default assumption. Bad intel or some other misunderstanding is a good default assumption, until evidence shows up to suggest otherwise.
As for IDF investigations: the Dutch air-force accidentally killed 70 civilians in Iraq in 2015. It took almost a decade for that to come out. And because of a whistleblower. It was hidden from Parliament too. Militaries around the world are not known for transparency. So we may indeed never know. But stuff leaks, and whisleblowes are out there.

Press coverage of this war between Israel and various Iran proxies is extremely high, e.g. compared to Saudi Arabia vs. Jemen (also Iran). The fact that a bunch of mortars fired at a UN compound even makes the news is absurd. These things happen in all wars (though usually there's no UN or journalist around to get shot in the first place).
Nobody is complaining that Mexican drug cartels don't allow enough journalists on the battlefield. Of course it's fair to hold a democratic county to the highest possible standard.
I'm sure there's both good and malicious reasons why journalists are not given free
and safe access to this war zone. From the other side I'm skeptical that Hamas and Hezbollah will protect every journalist no matter how critical their reporting.
This creates an asymmetry where anytime Israel allows a journalist in, they will only report on bad things done by Israel because otherwise they're killed. Or they get killed by accident by the IDF. There's no upside. But denying them access also looks bad, and isn't how democracies should behave. Embedded journalists in the IDF would be safe and might reveal bad behavior from the other side, but it would be seen as propaganda. Which it is, but so is Al Jazeera coverage. There's no winning strategy here.
And then of course Netanyahu and/or his zealot buddies will find a way to make things even worse. And because this is the middle east, it's always even more complicated.
From a news consumer point of view the best thing is to probably just wait.

Presumably they have to reason to believe Hezbollah is using those locations. I don't know how accurate their intel is of course, but neither do most people who comment on this sort of stuff.
Perhaps a more important question is why on Earth the UN is still there. They never stopped Hezbollah. They can't stop Israel either. Seems they're just in the way? But maybe I'm too cynical.

Just watched the whole thing. It's great until it goes off the rails in the last fifteen minutes. I think it's Roger Ver and Amir Taaki that sent the documentary maker chasing a ghost. They made RBF seem important, even suspecting it to be a government sabotage effort. This glorifies @npub1ej4…ndrm's image in his head, which Peter then openly exploited - while being very honest about doing so.
The bigger meta mistake the documentary maker made was to seek out people who enjoy being on TV. If he'd contacted experts in a more systematic way they would have ruined the plot. But this is more fun for everyone. #note1w06…nkww

Silent Payment syncing on a full node, which you should have anyway, should add less than 1% overhead.
For light clients there isn't even a full spec yet on how to do that, so I'm not sure what mechanism you used. It should be comparable to bip158 sync.
In any case Silent Payments are just a way to avoid address reuse, they're not trying to achieve the same thing as Monero.
