Did Trump go too far insulting European soldiers who died fighting for America?

One of the big stories in European papers today, particularly UK ones is Trumps comments on how other NATO nations wouldn't help the US and how they stayed away from the front lines in Afghanistan after 9/11

Over 1100 non Americans died in the conflict, including 457 British troops, and there's been cross-party outrage at his comments.

However, looking through social media and newspaper comment sections, I'm seeing lots of Americans praising Trump's trolling and labelling those having concerns at his comments as having TDS.

So thoughts, has Trump gone too far by mocking the fallen? Or do those offended have TDS?

Well Trump has had his bottom spanked by the King and he's made a grovelling apology.
