I think the question people of the US (not just the US, but that's the one we're talking about) should ask themselves is: "What have I done that led to this, and what can I do to make it better?".
A country is a place run by its people, in this wonderful age of democracy. In a way, Trump's victory is a declaration of the rule of the people. We all make mistakes sometimes, and from what I observe, national politics as a model isn't much different from decisions of a single, often immature person. The fact that you guys strove for change is a great sight, even if it's a shame towards what the change has been so far.
None of you guys can lift the whole country on your shoulders, but if you gather up, you can achieve great change. With proper moral leadership, it can be a change for the better, which is what I'm hoping for dearly for your country. I love the way it is, and it makes me sad to see it fall apart so rapidly.
It's far from over, the US, but the damage to its image and structure piles up swiftly under Trump and Co.'s rule. The history will remember Trump for a while, I imagine, but it's what's going on now that matters. United States is very much capable of getting shit done - but only as long as people contribute to that greater cause.
