It's interesting that you bring up climate change in the context of fusion. Because even in optimistic scenarios fusion will only play a role in a couple of decades. If we want to do something about climate change we have to do it within the next 10-20 years - and nuclear fusion certainly won't play a role in that timeframe.

Also saying you want to try "everything" without considering potential downsides seems strange to me. There's only so much money there to spend. And I think there are other technologies more promising and more needed that would need better funding (e.g. new energy storage methods could need some support).

The 6 billion is not the number this will cost. This is the original number that is now deprecated by a much higher number. And the comparison to the German renewable costs is comparing apples and oranges. Germany spends this money on electricity generation, which is a very different thing from funding a technology which may or may not produce energy in a distant future.
