The whole citizenship/nationality/identity thing is very strange for people who have moved around. When I was growing up in Singapore, some 'very British' guys my age were highly surprised to be called up for Singapore National Service, having lived there basically all their lives. One 'white British' friend became virtually stateless when his UK passport expired, as he had been born in KL, and both his parents in Madras (as it was) and he struggled to show to the British HC why he was in any sense British at all! Both my sons are dual UK / US Citizens, even though neither of them really has any meaningful connection to the USA - they will get a nasty surprise when they get a call from the IRS or the Draft Board! My mother, born and raised in the Netherlands was a dual, but renounced her Dutch citizenship, saying "It's because I just can't get on with Dutch people".
