I would not think that IH would be providing "engineers and labs," and I'm not sure that they have them to provide.
Apparently IH does have engineers and labs that are available for promising NiH track research.
The dispute with Rossi would be irrelevant.
It appears to be relevant according to Dewey.
My sense is that Dewey might be distancing IH from Brillouin because it does not help the current narrative with Rossi.
