This seems like a bit of a silly point, given that the war in Ukraine is, at least so far, nothing compared to the conflicts of the past. Do we wanna rush head first back into something that reliably produced worse conflicts than we see today simply because what we have going now isn't perfect?
>Germany’s dependence on Russian gas is now limiting its ability to respond to a crisis. They’ve handicapped themselves and can no longer promote peace and in fact are funding a war.
A bunch of western companies are pulling out of Russia over this and it looks like the whole thing is going worse for the aggressors here than they expected. I'll take this over Germany and Russia engaging directly in armed conflict.
In many ways, the theory that interconnected trade promotes peace is similar to the neo-liberal economic view that globalization promotes lower prices and thus more efficient economies. Such a view has been shown to be an over-simplification and ignores important side-effects of changing trade balances, such as rising economic inequality and the rise of populism.
The problem with that logic is that it only kinda works for large, powerful, rich countries as they are the only ones with any leverage. This is also highlighted by your own comment when you refer to China, EU, Russia, and we can add US and a few other countries to the mix.
Everyone else is screwed, as shown by the Ukraine invasion, China's constant sea-land grab in the South China Sea, China trying to land grab against India and Bhutan, and so on. So, regardless of how we may want the above to work, the old rules still apply.
In fact I'll say it's made it worse, since now US and China are dependent on each other to not engage in a direct war, but that means China is now free to screw around everyone else without worrying about US interference.
In case of Russia and EU's dependence on its oil, Russia tried to call the bluff and failed, but the EU is still not interfering and Russia oil was sanctioned just recently. So, it turned out bad for Ukraine.
Not Ukraine. If trade interdependence keeps democracies from defending other democracies, but doesn’t deter Russia, then it is counterproductive.
There is probably value in interdependence, but it can’t be blind interdependence - it needs to be conditional and truly multilateral. If EU depends more on Russian fossil fuels than Russia depends on EU imports, it isn’t really interdependence.
>The reason we’re not in a world war right now is
Nukes.
If I recall correctly, the "interconnectedness" of Europe of the Early 1900s was thought to be the reason that a large war was not possible.
Perhaps increased trade will help nations to settle smaller disputes via diplomacy but the outbreak of war seems to be something can defy rational explanation. That is, we can't always expect that the leaders and citizens of aggressor countries are making rational decisions.
