I found this article which seems to relate to the chart:
Under the Volcano: What G-7 Leaders Will Argue About in Sicily
It elaborates more on each of the leaders' positions regarding the issues listed.
I guess I'm somewhat protectionist when it comes to global trade, at least when it encourages exploitation and leads to trade deficits, outsourcing, and an overall economic stagnation and decline. It stands to reason that Germany and Japan would favor free trade, as they're enjoying trade surpluses, but those getting the short end of the stick might not be as favorable to the idea.
As for climate change, I believe that it's real. I don't think the problem has to do whether or not people believe climate change is real. The real issue is that it's doubtful that very many people will want to do much about it. We're a society built on mass consumption and huge expenditures of energy, and an active effort (thanks to globalism) to expand as much of it all over the world. That's where it seems to be a difficult decision, since we want to help improve the industry and infrastructure for the developing world, but it would mean increasing carbon emissions.
Regarding immigration, Trump's position seems a bit erratic. I think all of the G7 countries are facing internal political differences over the question of immigration. I think we could try to come up with a more coherent policy ourselves, although it's doubtful in the current political atmosphere.
As for Russian relations, I think we can try to work things out with them. I don't really see that we have much other choice. Especially if we're concerned about ISIS, Iran, and North Korea, settling our issues with Russia and getting them on our side could prove enormously beneficial.
