Was that nuclear canal plan real, and did it become an oil route?

There was a real proposal in the early 1960s to study nuclear excavation for a canal across the Negev. That is quite different from an approved construction project: a proposal or feasibility study does not mean the canal was built, or that anyone began digging it.

The material included here doesn't establish the pipeline connection. A later oil pipeline and a nuclear canal proposal are separate claims unless there is evidence tying their routes and histories together.

I’d split this into three questions: Was a nuclear canal proposed? Was it ever built? And did a later pipeline follow its route? The first has a historical basis. The excerpt gives no evidence for the second or third, and it doesn’t substantiate the claims about Iranian or Emirati oil either.

To check those parts, look for the original proposal and independent records about the pipeline’s route and operations. Similar geography, by itself, wouldn’t show that one project grew out of the other.
