A process which has been finally accomplished at one of the most advanced research facilities in the world after decades of effort, and which requires as an energy input almost as much energy as the process produces, is not easily weaponized, no.
Fusion reactions are hard to start. To use one as a weapon would require you to deliver the fusion fuel together with a source of enough energy to start the fusion reaction off. So the most effective way to do so has historically been to trigger them with a nuclear fission reaction from an atomic bomb - which results in a Hydrogen bomb.
In other words, weaponizing fusion generally requires you to already have an extremely powerful weapon.
Weaponizing this laser based inertial confinement fusion approach requires you to deliver a facility the size of the Lawrence Livermore lab plus the electricity generating capacity of a significant part of the west coast of America onto your target.
