Energy Density
Fission:
>Thorium: 79,420,000 MJ/kg
>Uranium: 80,620,000 MJ/kg

Fusion
>Deuterium-Tritium Fusion: 337,387,388 MJ/kg
This means that Fusion generates over 4x energy at the same mass

Cost
>Thorium: $30/kg
>Uranium $73/kg

>Deuterium: $2400/kg
>Tritium: $30,000,000/kg
Fusion costs 410,000x more than Uranium. (Not including the cost of the plant)

Doesn't matter if ITER succeeds or not
Anyone who believes that Nuclear Fusion can happen in our lifetime is fed with lies.
There is not enough H-3 in the world to supply enough fusion energy, let alone supply it cheaply
The amount of advancements we have to do in order to make farming of H-3 cost-efficient doomed Fusion from the very start

We would need to make Nuclear Reprocessing of Nuclear Waste widely available just so we can generate enough H-3 cost-efficiently.
But to do that, the world must be required to accept Nuclear power as their baseload.

Fusion would not happen in 200 years and it cannot happen without Fission to back it up en mass. Both in power and fuel
