Amazing how people fail to read between the lines.  If our PM didn't show up, it was not because he forgot or didn't feel like it.  It would be a well-thought out diplomatic move aiming at a particular purpose (perhaps even kowtowing to Trump).

Say what you want about the Liberal government, but they have been very strong on the world stage and their leader, our Prime Minister, is an expert trained since he was very young to be on it.
