Of course, NATO, as I mentioned, is an extremely important commitment that Canada [Technical difficulty—Editor] has sunk substantial costs into. Right now we're hearing lots of questions about whether we should let Ukraine join NATO or join the EU. What about Finland and Sweden? Should they join NATO?
One thing that is clear is that 2% is clearly a political target. Two percent does not come from any sort of quantitative analysis. It doesn't come from any sort of strategic analysis or anything like that, and I can say that relatively confidently because, in doing my NATO research, I've looked at over 200 pieces of research published on NATO burden sharing—policy papers, books, articles and all of that. The first thing I can say is that 2% is something that politicians created, which defence budgets had to very much react to and try to attain afterwards.
I think there's another thing we should point out. Two percent, as some of my other colleagues have said, doesn't really say very much about what you're actually doing. My burden sharing research is bringing me more towards other institutions that NATO uses to share the burden, like the partnership for peace [Technical difficulty—Editor]. You may recall that Canada is hosting its first centre of excellence in the next several years on climate security and NATO, so this is one very important way in which states share the burden that essentially is not talked about when we look at central budgeting or when we look at civilian budgeting.
Also, I would add that the idea of expanding the alliance in an overnight-type way [Technical difficulty—Editor]. We have heard even Zelenskyy himself talk about this.
I published research in European Politics and Society in 2020, showing that it is not as easy as simply making a request. It's a process that can take from 10 to 15 years.
