I think you greatly underestimate the impact of the recent US administration on global opinion. If some Dutch people changed their mind about the US, so can diplomats and politicians.

How do you believe a country can maintain its hegemonic position if it does its utmost to reverse a hundred years of propaganda and cultural status?

I grew up in a culture that loved the USA. There are lots of countries where that's the opposite.

Can you define 'perception' and why it matters, especially on a global level?
