I believe that the "K" is only supposed to be used for International
Airports.

Not exactly correct. The K prefix is the way US airports are expressed
in the ICAO format. Not all US airports qualify, mut it's not just those that
are international. In order to make things "METAR" compliant, the FAA
went around and reidented everybody who reported surface observations
to the ICAO-compliant format.

I wonder how the good old USA got a "K" when Canada got a "C"
and Great Britain got a "G"?

In international radio the US gets K, W, N, and AA-AL. The A and N
date back to the Army and Navy original uses. I'm not sure how we got
K and W. The British and the former parts of the British Empire split
the G's and V's (except Canada gets C's as well).
