Ah, this new sovereignty you talk of, does it mean in effect no sovereignty, that all nations must now bow to a world order, a world sensibility of what is right and wrong; what is morally acceptable and what is not?  And who makes the pronouncement of what is acceptable behaviour, or in Trudeau's case, acceptable self flagellation, the globalist elite, like the social engineers currently having such fun with the concept of free speech?
No, what Trudeau did was take willful naivety to new heights.  What he did was reveal that Canada is led by a sniveling little baby that desperately needs mommy and daddy to pat him on the head and tell him what a good boy he is. 
This is no world leader.  This is a world class embarrassment.
