When has the US not been the bully?
A lot of people woke up to the news and had their initial "Are we the bad guys?" moment.
As a non American its pretty funny to watch.
I think the shock is more of a shift from the lawful evil spectrum, where the US either did things covertly or had a much better narrative prepared, to chaotic evil. Apparently Congress had no clue here, and Trump simply called them "leakers".
To be more blunt, we knew America was a pompous asshole, but it always pretended to be orderly. This is the US putting in a toupe and plucking its mustache. The act isn't surprising, the shift in attitude is.
How about when Carter made peace between Egypt and Israel? Carter also gave the canal back to Panama and normalized ties with China.
Carter may not have won the FIFA Peace Prize. But he did win the Nobel one. My father respected Carter more than almost any other living person, and I trust his judgement.
