The Tories were trying to "score some cheap political points" by looking for some answers. In much the same way the Russians were "grandstanding" about why the USAF and a couple of allied air forces felt the need to bomb a Syrian Army position on the first day of a recent truce.  In both cases the side with the answers opted for less than transparency.  

With the result in the Canadian case of looking like childish stooges and in the American one of risking a world war.  

Wise up!
