I think we mostly agree. Especially on the fact that we should be more ambitious and involved.
Maybe my NATO tilt comes from my own heritage and that I think that committing to the defence there in a meaningful way - primarily a flyover prepositioned division - will pay big dividends in trade and political influence. I see pulling back as highly counterproductive and a flyover division (heavily based on reservists) is a cost effective way of being involved. Except for a brief decade, Russia has been a constant threat for almost a century but, until recently, deterrence has worked. It will again.
I do see benefits in a bigger involvement in the Pacific theatre. But while I see a strong defence posture in Europe as deterring Russia, I do not see deterrence working with China. They have an agenda. They will take time with their agenda for as long as it takes for the balance of power to assure their victory stage by stage. IMHO they are smarter and more elegant in their methods than Russia or the US. If things get too rough in the Pacific, I see the US caving in and becoming isolationist before the Chinese change their aims and when that happens there is no chance of a credible deterrence in that theatre regardless of our involvement.
Whenever possible I try to avoid the Mercator view of the world. When you do that you see just how large Africa, India, the Middle East and Australia, even South America (including their resources) are in comparison to Europe and even Canada and the US. The world is changing in recognition of that and who the future big players will be is still up for grabs.
