Fusion energy is a very high risk and very long term investment. Meanwhile plenty of billions are being spent by governments and academic institutions (ok, arguably the same thing) around the world on fusion research. In almost every thread here on fusion someone eventually says something along the lines of "what we need for fusion is a Manhattan project", but ITER by itself is costing more than that in inflation adjusted terms. Fusion has soaked up massive investment and continues to do so.
