What a time to be alive. In fact, I think I now have all I need to start a war with my neighbours.

  you could have started a war with your neighbors using only sticks and stones - indeed, much of human history is people starting wars with their neighbors using weapons that we today would call primitive. But now you can start a very destructive war with your neighbors. Thanks to modern technology, you don't have to bother beating your neighbor to death with a wooden club, you now can annihilate them, and basically anything in their immediate vicinity, from a comfortable distance :D

    little unclear what drove the E-7 thing - my impression is that accelerationists on the political side wanted to push for space-based defense, and drove the attempt to cancel. it is a reasonable point that any airborne radar is an attractive target to long-range missile. and that if your radar is in space, it's a different, less available class of missile to attack it (and also that so far treating space as contested is taboo). the recent loss of THAAD radar should also make people rethink how to make an emitter that survives the first round of missiles.

How is DIY radar regulated by the FCC?

  You need a license for most frequencies.

  Emitting in the regulated part of the spectrum must comply with the regulations, regardless of the origin of the transmitter.

    There are actually a few exempted categories, such as test and measurement equipment (because something like a signal generator can obviously generate whatever the user selects).
