Well we're getting into political territory, but recently that "subsidized" seems to have swiftly changed to "threatened", so, I don't know. What you say used to be true in the past, but it's not so clear anymore.
Also: only country that ever invoked article 5 was actually the US. In that sense the opposite is true ("lots of countries have subsidized US defense"). The US "subsidy" came from the strong conviction that "US would act if we needed it", but that conviction is quickly evaporating.
