.com, .org and nearly all original TLDs are used internationally, though there are also local derivatives like co.uk. Even .edu used to be available internationally. I suppose most people have realized by now that .gov is strictly US, but it's not like that was obvious from the naming scheme alone.
I was under the impression that the US government controls / owns .gov
Yes exactly. So there's no need to use gov.us, but there isn't a 'ukgov' TLD, so gov.uk makes sense.

Yes, exactly. .gov is US-specific and controlled by the US government.
Or .edu vs. .ac.uk; .mil vs. .mod.uk.
They got there first and just spread over TLDs before consigning other nations to fit under one I suppose.
