That's... I don't even know what to call it. Much folly. You are not unaware that the reality of world politics is a a competition for power. Other countries do not have your best interests at heart. Fuck, they probably don't even have your interests at heart at all.
And you believe that our politicians do have our best interests at heart?
They certainly have at heart better interest of yours than Putin.
Sorry, but I think that's a little naive. They have more in common with each other than they do with us. They have more to gain from coordinated engineering of a global culture of learned helplessness, subservience, divisiveness, and confusion for shared benefit in that struggle than they do from worrying about the well-being of their own citizens. The only counter-point is the allure as a world leader of the nation one leads being more powerful than another's, and those games are still played for sure. But I have no doubt that they're willing to lay those games aside at any time for shared interest. You can see this with the case of Julian Assange, for example.
The foremost struggles of the day are class and environment, and they are global struggles. Rising in intensity everywhere. The sides in this struggle are the people vs the ultra-wealthy and those who serve them, which includes politicians. And while the people are locked within borders, the ultra-wealthy have near unlimited ability to pick up and put down wherever they please, cultivate simultaneous operations for their own interest all over the world, and act as unfathomable black holes of influence on whatever land they touch. You really think the Walmart family cares whether America or China is more powerful? Of course not. Their position as the richest family in the world is dependent on the slavery conditions of both Chinese and American workers, and the economic capture of American consumers. The only sense in which they'd want America and China to care about conflict with each other is as an excuse for their governments to proliferate totalitarian infrastructure under the guise of global political conflict, which can then be aimed at keeping workers in both countries in line.
