It is a bit paradoxical of course, since, as you pointed out, the British empire is the reason that the US speaks english. However, I would still argue that the US is really the reason English became widely spoken in Europe.
The British Empire dominated large parts of the world, but it never dominated continental Europe. English was not widely spoken or taught in Europe until the end of WW2, when American culture became highly influential (although the UK did have its part through pop music).
The final push for English came with the internet and thus again from the US, I think. In many European countries there is a big divide in terms of English proficiency between people who grew up in pre or post internet era.
