I appreciate the sentiment and I’ve felt similarly of late, but we don’t want to “empty the chamber” all at once.
One of the risks of escalation is that the other side may stop fearing what you’re going to do next. This is what happened with Iran: they no longer have any fear of the US whatsoever.
I know Trump is never going to fear anything Canada can do, but ordinary Americans may still worry. We should be trying to turn up the pressure slowly, and make sure that Americans keep turning against Trump rather than starting to see Canadians as the enemy, which is what he wants.
