Yet you likely supported Trump's dream of expanding the American nuclear arsenal and the idea that nuking NK would be a good idea! Trudeau is correct that the ones to be doing the talking need to be those with the arms: i.e.Russia, the US, the UK, France (I think), India, Pakistan, Israel (which won't even admit that it has any) and North Korea. Treaties like SALT are the ones that have validity but Israel and North Korea for two would never sign up to that. The landmine agreement was a more manageable task and far more countries used them.
