That is how it is reasonable to interpret the headline, given no other information

I don’t know how to discuss this because I have no idea how you came to that conclusion.

It seems like a totally straightforward headline to me. There’s no mention of per-capita, no mention of some sort of multiplier.

It actually seems like quite a generous headline to me, given that it is talking about just the US government (when most of our healthcare system is privately paid).

Perhaps you could tell me what information, other than how big the US is, is conveyed by the headline when it says "than six countries... combined".

I don’t disagree that the comparison could be better, but that’s a different problem from a misleading headline.
