"Everybody knows that Justin Trudeau is not about to invite Mr. Khadr to Ottawa and apologize to him in person. He’s too cowardly for that."
As so often happens, the slanderer accuses her victim of a weakness or failure that applies better to herself.  In this case, hiding behind the shield of journalistic privilege makes it safe to accuse the Prime Minister of cowardice - a trait that is totally foreign to his nature.
Ms. Wente gives no argument why the PM should invite Mr. Khadr to Ottawa.  In fact everything she writes would suggest the opposite.  Nevertheless she is unable to resist taking the cheap shot - not very civil and not very brave.
