it’s not a twenty year old paper, it’s a twenty two year old preprint which has all the reliability of a blog post. in 22 years, you can get born, complete all education bachelors degree, start masters degree and write a real paper that would be accepted in a real physics journal. the reason it’s not accepted for all these years is it is packed full of crackpot nonsense. it cites Dan Brown’s Angels and Demons ffs

you’re off by something like 15-18 orders of magnitude

israel isn’t wedged between france and germany, and operating station like this undetected out of a car would be almost impossible even for professional

it’s all coming from a report of new numbers station popping up. some radio listeners dubbed it V32. it indeed transmits in farsi, and transmissions like this were historically used by spies

however, by now source of transmission was located somewhere between northern italy and netherlands, and iranian jammers try to disrupt its operations. that is, someone is transmitting from western europe towards iran, and iran doesn’t like it, meaning it’s not them. everybody writing “iran might be activating sleeper cells” as a response to this is full of shit or has no idea what they’re talking about (it might be just a psyop targeted at irgc and friends)

variety of guided weapons like jdam or hellfire are generally much cheaper (easily 10x or more) and more available than air defense interceptors, not even mentioning lead times for them (usaf has effectively unlimited jdams). what is happening now is bigger version of desert storm scud hunt. does it work? if you accept proxy measures, according to some randos on twitter that tally them, then missile-related air raid alerts in israel dropped significantly in first four days

your guess is correct. at minimum, truck needs to transport several meter long, couple to couple tens of tons heavy tube without destroying it, then put it upright, at some point input target location and launch, which requires some kind of communication with missile. solid fueled missile can be stored ready for launch, but liquid fueled missiles also require infrastructure to handle incredibly toxic and corrosive fuel
