It would have been better if 20 billion of the half trillion dollars used to make the failed HIV vaccines were used to build the SST so that particle physics could get back on track.
Nope. Wrong. All physics is not particle physics, by any means, which is what you're actually saying. And there were a few OTHER sciences involved (like chemistry). Building gigantic accelerators buried in giant holes in the ground in Texas was and is ludicrous. (and it would still be ludicrous if located elsewhere in the US besides Texas).
