No, nuance would be for example to understand that while the US are a country with lots of influence and power, its president is actually not that powerful given the current situation. The president is bound by so many conflicting interests, contracts, party politics, strategic considerations etc. pp. that his leeway is probably quite small.

In my eyes it's not just out of touch with reality but also naive to think along the lines of: "Why don't the politicians just do the good thing? It's so simple, just do the good thing. Now because I care about this topic so much that I'm very disappointed that he hasn't used his supreme powers to change the world, I'm not gonna vote for him. Actions have consequences".

Sure, everyone is allowed to practice wishful thinking. But politics won't change.
