It was ruled out in the late 1940ís. It wonít even work in a ocean of
pure Deuterium and Tritium, and the composition of the gas giant planets
are about a billion times less fusion friendly than that. The only way
they got it to work in the H bomb is use clever geometry so that one
fission bomb compress the fuel and then at just the right instant
another fission bomb heats it.

Just setting a bomb off in a ocean of fuel will do nothing, thatís why
it took 7 years after the invention of fission bombs to figure out how
to make a H Bomb.
