Though laughing about the current regime in USA is an understandable reaction, it's also at the same time not a laughing matter at all. It's a bit like a great comedian or clown who is very entertaining and goofy at first but at the end he randomly kills 1 person from the audience. Still a funny act? No. Because at the end of this craziness, people will needlessly suffer and/or die.
The country still has huge world-wide influence, and if that influence originates from crazies, that's not great for anyone, neither for US citizens nor for any other country in the world which has to at least partly deal with the US somehow. It is, however, a great and very visible warning sign for other countries to hopefully not follow the US into such craziness.
I know, but it's still a warning sign, even when some can't read or understand it.
