Another good example would be actions Brits took in order to protect the fact that Enigma was broken. For example, when Enigma deciphering indicated that there's warship in a specific area, they would send spotter plane first before attacking it, in order to provide enemy alternative explanation as of how they were discovered. Some operations were aborted entirely for this reason
Dense motherfucker doesn't know where his bread is buttered. Status of dollar as global reserve currency hinges on free maritime trade, on top of sheer amount of oil that passes through that place and american sensitivity to energy prices
Not to mention that they're cause of greater share of instability in the region
sorry for being unclear, i forgor a word. what i meant that certain antenna designs would have specific fractional bandwidth, so that just scaling that design to higher frequency makes usable bandwidth wider in kHz terms. in order to get higher fractional bandwidth more complex or bulkier designs would be required, like thicker conductors, added parasitics, something LPDA-shaped, or maybe elaborate matching circuit, all of which cost money. i guess that while resonant amplifiers are a thing, probably bigger limitation would be bandwidth of mixer
i'd also note that antennas, amplifiers and so on have bandwidth that is some % of carrier frequency, depending on design, so just going up in frequency makes bandwidth bigger. getting higher % of bandwidth requires more sophisticated, more expensive, heavier designs. LoRa is much slower, caused by narrowed bandwidth but also because it's more noise-resistant
that key to heaven was probably something between mistranslation and bs, but there's so many more awful shit!
electric swamp - iraq used swamps as a natural barrier, laying mines, placing mortars and HMGs around, and also putting high voltage wires in water. when iranian raid was detected, they'd just fire a bit until iranians fell to water, then turned power on
BWR fights - phoenix missiles on iranian tomcats. iraqis had no idea what's going on to the point that they suspected sabotage (mirages just fell apart in air for no reason)
war profiteering - lots of countries sold covertly weapons to iraq or to both sides, but swiss were probably worst: they sold gas masks to iran and chemical weapons precursors to iraq
ww1 era warfare complete with said chemical weapons, and also genocide of Kurds for some reason
and all for nothing (result: status quo ante bellum)
cyanide doesn't accumulate, it can be broken down in some hours (very small amounts of course). otoh many heavy metals do behave this way, maybe you worked with both at the same time
all metals that bind to sulfur well are to some degree poisonous. these are lead, mercury, thallium, some platinides (in salt form), arsenic, and also copper, but less than others. some metals have other mechanisms of toxicity, like nickel, hexavalent chromium, cadmium, beryllium or barium. some of these accumulate in brain or bones, and some don't. some are more toxic when inhaled like zinc or chromium
you also get points for historical accuracy, as it was used as far back as ancient rome
also, how low tech is low tech? Litvinenko was dying for three weeks after polonium poisoning, and radium will have similar effects, first extracted 1898
I know that Abe was PM since always, but he's dead for almost three years now
