I agree with your comment regarding fairer distribution, but I think when we look at globalisation's impact on war, I'm not sure this is really playing out.
Iran has not benefitted hugely from globalisation (unless I'm missing something), however because of globalisation and their ability to impact the global economy, they have an outsized hand to play relative to their GDP.
Did Iran as a country participate in the global economy outside of trading their commodities? Commodity trading existed well before the global economy and was often a cause for wars. I was under the impression Iran was fairly shut down from the rest of the world economically and culturally.
