Does Trudeau really think that Canadians and Americans are this stupid? He prevented a full security review of the sale of the company, because he knew that it wouldn't pass the review. This is similar to the situation with ITF Technologies, the military fibre-laser technology company, the sale of which Harper blocked after it failed to pass a security review, which Trudeau later overrode to allow China to buy the company. 

It's simple: Trudeau is for some reason willing to let the Chinese buy crucial North American military/security corporations that do not pass a full security audit. Why? Was it just the (illegal) campaign contributions and contributions to the PE Trudeau Foundation? Is it pressure from Quebec corporations that want to do more business with China? Or is it something else? What is the reason for selling us out to the Chinese?
