One's best friend tells the best friend when best friend is wrong. It does not join the best friend in the objectionable activity. Afghanistan was a perfect example. I was appalled when the US attacked Afghanistan. Any other country attacking that poor nation and I would expect that Canada would be on the side of the Afghans. Instead we joined in the attack!!
Now? .We withdraw from NATO. We have done our job keeping the US and the USSR, then Russia, apart. Hopefully the US will pull out of NATO as well. Trump's relationship with Putin could be a the greatest asset.
I do wonder what would have happened if Austria had refused to join Germany in the 1930s. After all Canada is to the US as Austria was to Germany.
