In the 90's when oil was cheap, the iter project (a new fusion reactor) was too expensive and nobody wanted to pay. Make it cheaper, make it smaller. So the design became more modest (for lack of a better word). Early 00's, the iraq war was on. France was against So out of spite, the US sided with japan as host country, rather than with France as expected. This blocked approval of the build site for several years. Late 00's, oil is at record prices and the a build site (Cadarache in France) is finally selected. With a question attached (or so I heard from people within my field), if we pay more can you speed up the process? Yeah right, unfortunately science and engineering does not always work that way (mythical man month). Some things just require time. Until iter, the development of fusion went faster than the development of computer hardware. This delay of about ten years for financial and political reasons will come back to haunt us. Blame your governments for being cheap and petty. Blame your governments that we won't have fusion in time to save our sorry asses.
