  • Personally I tend to think that the Bengal famine is better compared to the Holodomor, as it is closer in time, area, and effect. If there is a lesson to these things though, I think it’s that it doesn’t matter what economic system you use of the people in charge are fans of eugenics, and that’s why it’s so important that there be strong independent checks on the government and politicians, minority representation, multi-party rule, etc…

    Note, since the 80s the vast, vast majority of piston driven aircraft engines have been able to operate on unleaded fuel. We know this because for decades GA pilots have been filling out the paperwork for an experimental fuel variance and then running these engines unmodified on the cheaper unleaded they got from the gas station down the street without any apparent issue or rise in engine maintenance/failures among pilots that do this. The main hurdles being the necessary and not insignificant paperwork as well as concern over insurance rates.

    From my understanding there was a problem with one series of engine in the seventies that was suspected to be due to unleaded fuel among the more modern product line of a major manufacturer, and while the engine was modified to fix it neither Lycoming nor Continental, the two primary piston engine manufacturers who make up the vast majority of the market, saw significant pressure to drop the official recommendation for unleaded until relatively recently.

    Since the US finally started to get serious about phasing out leaded avgas in the 2010s, and the aditude of its been fine so far so why risk any change has run up against said pressure, both have to my knowledge dropped the requirement retroactively with no modification necessary for the majority of their historical and current product line.

    You might need to re-engine or more likely just get an exemption for flying history aircraft, but the benefit to the hundreds of thousands that live near GA airports in terms of reduced damage to children’s nervous systems far outweighs the nebulous cost of switching the default form of avgas.







  • I mean Saudi Arabia also does all those things, most of them far better than Israel ever could due to geography, and at a far lower cost. If Isreal snapped out of existence tomorrow, between Saudi Arabia, Iraq, and Greece European and North American power projection in the Middle East and North Africa remains almost entirely unchanged.

    Honestly the military benefits of supporting Isreal while real are definitely not as important as the domestic political benefits to the US, which is to say that the conservatives like Isreal because it provides a nice place to deport all the Jews to while also maintaining precedent for an enthnostate with race based citizenship, and the Democrats like it because they get a lot of gifts, friends, and in their minds potential voters, all for doing exactly what the conservatives want them to do.

    To expand on this, we also have mapped it out and know that the amount of dark matter varies wildly between galaxies, with some having basically none while others have far more dark matter than observable matter in them. There’s also a lot of stuff with the early universe that only works if you have something with gravity that doesn’t otherwise interact significantly with matter.

    As Angela Collier puts it, dark matter is not a theory, it is a set of observations.
