Does It Really Matter Where the B117 Variant of Covid-19 Originated?

It's been suggested by 2 million analyses of previous tests, that the highly contagious 'British' B117 variant of Covid-19 was in the US as early as October 2020 (https://www.theguardian.com/world/2021/jan/01/now-coronavirus-variant-us-since-october). The variant has a characteristic S gene drop out but you wouldn't know this unless you were looking at the sequence. Identification of a high incidence of B117 in Southern England, led the UK having their travellers banned (or subject to extra checks) by a wide range of countries. Now medical teams are looking for it, the variant does appear to have reached a wide range of countries. Just a couple of points. Countries that do sequencing on the virus are more likely to find mutations, before other countries that don't routinely do such screening. The rapid human transport systems that link the planet's countries, are likely to distribute a variant before it has been detected. So it's a bit futile to 'blame' a particular country for being 'responsible' for a variant. Detection, elsewhere, is likely to follow, when people start looking for it. We are, in one sense, all in this thing together. Each country will only become substantially safer, when all variants of Covid-19 are substantially eradicated throughout the world (and in all actual and potential hosts). We need the vaccines to reach all people (including in the poorest nations) as fast as possible.
