That photo could easily be interpreted as saying, "Dude, not only my country but my political family is a different breed than the Trumps, far more left, and I'm keeping an eye on you like my dad did but don't mistake proximity and strategic silence for support if push ever comes to shove. We don't share many of your values."

With respect, Leah misses the fact that Trudeau's reputation precedes him. Trump knows all about Trudeau's stance on refugees and immigrants, the inclusivity piece regarding women, support for gay rights and abortion, socialized medicine, Trudeau's fawning eulogy for Castro, everything.  Plus, Trudeau reiterated when asked by American press this country's policy on immigration. It was more a surprise to me that Trump did not freak out on Trudeau.

Plus, negotiations haven't even started yet. General political decorum dictates niceties at this stage, U.N. style.
