Fission has a few unavoidable issues: long radioactive isotope half-life, weapons proliferation, and the runaway scenario. Fusion has none of these issues plus the fuel being abundant. It's the answer to the question "how do we meet the growing energy demands of humans over the next thousand years?".
The only real danger is that of a tritium leak, but the short half-life makes the prospect of a leak less concerning.
