This weekly roundup thread is intended for all culture war posts. 'Culture war' is vaguely defined, but it basically means controversial issues that fall along set tribal lines. Arguments over culture war issues generate a lot of heat and little light, and few deeply entrenched people ever change their minds. This thread is for voicing opinions and analyzing the state of the discussion while trying to optimize for light over heat.
Optimistically, we think that engaging with people you disagree with is worth your time, and so is being nice! Pessimistically, there are many dynamics that can lead discussions on Culture War topics to become unproductive. There's a human tendency to divide along tribal lines, praising your ingroup and vilifying your outgroup - and if you think you find it easy to criticize your ingroup, then it may be that your outgroup is not who you think it is. Extremists with opposing positions can feed off each other, highlighting each other's worst points to justify their own angry rhetoric, which becomes in turn a new example of bad behavior for the other side to highlight.
We would like to avoid these negative dynamics. Accordingly, we ask that you do not use this thread for waging the Culture War. Examples of waging the Culture War:
-
Shaming.
-
Attempting to 'build consensus' or enforce ideological conformity.
-
Making sweeping generalizations to vilify a group you dislike.
-
Recruiting for a cause.
-
Posting links that could be summarized as 'Boo outgroup!' Basically, if your content is 'Can you believe what Those People did this week?' then you should either refrain from posting, or do some very patient work to contextualize and/or steel-man the relevant viewpoint.
In general, you should argue to understand, not to win. This thread is not territory to be claimed by one group or another; indeed, the aim is to have many different viewpoints represented here. Thus, we also ask that you follow some guidelines:
-
Speak plainly. Avoid sarcasm and mockery. When disagreeing with someone, state your objections explicitly.
-
Be as precise and charitable as you can. Don't paraphrase unflatteringly.
-
Don't imply that someone said something they did not say, even if you think it follows from what they said.
-
Write like everyone is reading and you want them to be included in the discussion.
On an ad hoc basis, the mods will try to compile a list of the best posts/comments from the previous week, posted in Quality Contribution threads and archived at /r/TheThread. You may nominate a comment for this list by clicking on 'report' at the bottom of the post and typing 'Actually a quality contribution' as the report reason.

Notes -
IIRC it’s a liquid explosive that’s injected into the battery, so there’s nothing physical to check for.
Lol no. That'd mean inventing a whole new type of explosive that can be inside an working battery ?
Why - more likely these are custom made batteries no one thought to x-ray which were modified to have lower capacity and the empty space was taken up by a detonator and explosive. Much simpler.
What worries me is that the explosive compound might not exist at all. Maybe this is something that all lithium-ion batteries can do with the right command.
Rednecks blowing up batteries would have discovered it by now.

Come on. Short the battery, see if the effect is just as bad as a normal battery. Use sympathetic detonation to test if it is explosive. Use mass spectroscopy to test the chemical composition.
Other than that, a pretty ballsy power move by Mossad, betting on Hezbollah being to stupid to check for explosives in other electronics after learning that explosives were hidden in some of them.
Then again, any senior commander who personally handles electronics within 24h after learning that some of them had a tendency to explode is simply to trusting to live.
This won't do anything (other than causing a potential fire).
Explosives like that require an initial shock to actually detonate and overheating just sets them on fire (like it can set a regular battery).
If I had to hide an electronically ignited bomb in a battery, I would try to set it up so that a short ignites a primer which will ignite the explosive. Fill an electrical fuse with a primer which is volatile enough that the molten wire sets it off, perhaps?
The alternatives being that you have three leads on your battery (e.g. +, -, boom, where connecting boom with + will cause the explosion.), which is much more noticeable, or having another component which serves as a primer on the PCB near that battery. Of course, 'shorten the battery when receiving a particular message' is not a standard feature of most pagers, so you have to modify or swap the PCB anyhow, and putting the electronic ignition in there might be easier.
I concede that just because a battery is not rigged to explode on short it might still explode in other conditions.
Quite a lot of lipo have more than two leads, starting at a third thermistor wire, going up to per cell voltage leads, and eventually going to annoying Apple bullshit.
And even with two leads, if you're manufacturing a thousand battery-bombs, there's a lot of ways to do a one-wire (and ground) protocol to pass data to a microcontroller, which can easily be the size of a grain of rice. Or you could hard-short the battery leads on a battery without builtin overcurrent protections, and use it as a primary for your real explosives -- even a well-contained lipo fire is definitely hot enough to set off most thermal-ignite explosives.

Explosives like what? AFAIK the pager bombs were triggered by heat rather than shock.
PETN and any other similar explosives with enough power in such small size. At least PETN can be triggered by a spark which is simple enough to generate electronically (you just need a small transformer to produce high voltage and a very short spark gap).

Even if Hezbollah was checking (and we don't know they weren't), this is an extremely fast turn-around. The second tower was hit an hour within the first, and it doesn't really project incompetence that it wasn't protected sooner.
