Yes, it did facilitate providing proof of the Higgs, but hasn't done anything since then. Begs the question if building an even larger, costlier linear accelerator. LHC is down now, getting a power upgrade. Still, spending $15B and finding something (the Higgs) is better than to have spend $150 billion for nothing (ISS).
