I don't hate the entire nation, no.
I just disapprove of a lot of their policies, am sceptical of a lot of the things their government does, and direct my hate (which is largely fuelled by fear) at some very specific people. Like Donald Trump, and the facist tide he seems to have unleashed onto American politics.
Nowhere is perfect, obviously. There are a LOT of issues where I live as well (Sweden - if anyone ever tells you we're a fairytale country to live in, they're lying to you), but the domestic politics of my country don't have anywhere near the same impact on the global stage as the domestic politics of the US. When we pick a new Prime Minister, we just... pick a new Prime Minister and the rest of the world shrugs and gets on with it.
When the US picks a new President, the rest of us cross our fingers and hope like hell they're a good one, or we're up for four years of shittiness on a global scale.
Of course, like all of us, my perspective is coloured by the country where I grew up, and it's difficult for a resident in a European nation to fully grasp the complexities of political culture in the US - just as it's difficult for a US-resident to grasp the complexities of our political culture.
