Well yes, the current issue is that the systems were designed way ahead of the computational power to assess how the plasma would behave in such conditions so dealing with fluid instabilities that arises from the most microscopic of target asymmetriea occupies the bulk of their time.

If they had another 4 billion dollars to build the system entirely from scratch I actually think they could get fusion based on what they know now. But they don't and it works for weapons complex integration with is in the end what the DOE cares about so yeah
