Some puzzling stuff, here: 

Saudi Arabian officials have argued that military purchases ... should be seen as a goodwill gesture by the Islamic kingdom to cement its friendship with Canada."  Okay, on that basis, I don't think Canada should care.  Oh, but if that "friendship cement" comes with $15 billion pay-out, helping to finance 3,000 jobs, well, hmmm...

And this: "...other unrelated Canadian companies such as Terradyne have been making their  own combat machine sales to the Saudis."  Wow: how much are THEY worth?  And, is these deals government-backed contracts? And so what? Are these deals okay by the government or  not?

Also this head-scratcher:  "...reports that show older Canadian-made combat vehicles taking part in the bloody civil war in Yemen – a use for the machines that was not contemplated when Canada sold them to Saudi Arabia to maintain internal security."

Hey, wait!  Isn't putting down dissent in a Saudi province a matter of maintaining "Internal security"?
