No prob.

Warm and fuzzy has no upside anyway, apparently.

Do you think it can be iterated?

I suspect that if it doesn't work, it's just going to be the ultimate white elephant, rather than a disaster.

It is a white elephant. They'll learn stuff from it. Mostly they'll learn what they really already know:

1) controlled >unity fusion is hard
2) really hard
3) and stupid expensive.

So.. like...
I read a few articles on the topic.
A bunch of folks have been trying to use lasers to compress hydrogen until 2H2 -> He reactions take place, with the hope that heat from the photons to be released could be used to power the lasers and to electroplate water to generate more free hydrogen. The hydrogen keeps chaotically slipping between the lasers, going asymmetrical and failing to compress far enough. So they're trying more and more lasers coming from more and more directions. ITER takes a different approach, using magnets to compress a proton plasma.
I dunno. I think the failures could lead to some new basic science, though.

Probably materials science is getting the most benefit. I wonder how many papers have been submitted and accepted as a direct or indirect result of this? I'm not even sure how to find that out. Hopefully something more sexy than Velcro (not that Velcro isn't sexy).

But it won't lead to watts on the grid.

Sun Tzu said that, and I'd say he knows a little bit more about fighting than you do, pal, because he invented it, and then he perfected it so that no living man could best him in the ring of honor. Then, he used his fight money to buy two of every animal on earth, and then he herded them onto a boat, and then he beat the crap out of every single one. And from that day forward any time a bunch of animals are together in one place it's called a zoo! (Beat) Unless it's a farm!"

World’s Largest Nuclear Fusion Experiment Clears Milestone

The International Thermonuclear Experimental Reactor is set to launch operations in 2025
https://www.scientificamerican.com/arti ... milestone/

The truth is nothing like the headline.
A multination project to build a fusion reactor cleared a milestone yesterday and is now 6 ½ years away from “First Plasma,” officials announced.
First Plasma is hot gas. It's not self-sustaining. It's not breakeven. It's not even fusion. We'll have to wait another 50 years for all that.

The best way to get energy from fusion is to simply gather sufficient hydrogen together, and let gravity do the rest in building the fusion reactor. Of course, it's still very radioactive and dangerous, but if you put it far enough away, say over ninety million miles, then you can harvest a negligible fraction of the power generated (but still a useful amount) using silicon photocells.

You can also harvest energy by even more indirect means, such as allowing the radiation energy to generate air currents and using those currents to turn turbines - or allowing the energy to evaporate water, deposit that water on high ground, and then run the water through water-wheels as it returns back to lower levels.

Although the whole system is laughably inefficient, it can still generate electrical power more economically and practically than any attempts, so far, to carry out fusion on a smaller scale closer to where the electrical power is needed.
