Dutch Prime Minister Mark Rutte was interviewed by Mehreen Khan in the Financial Times, (“Dutch leader ready to be EU champion on free trade", (FT, 27-03-2018, p. 7), as part of his publicity campaign to position himself as the go-to free-market Conservative Liberal after Brexit. He went on record as saying that "The Netherlands, since the 16th century, has always been trying to maintain the balance between the great powers - France, Germany, and the UK" and that free trade is "part of the Dutch DNA".
Whatever the Free-trade DNA (has this taken over from the equally fabled Dutch moralism and tolerance?), Rutte, who has studied history, should know that he is off by at least a century with his 16th-cetury flourish. it is arguably wrong to date a balance-of-power policy to the pre-1670. But ethnotyping is just that: bad history dressed up as a timeless national characteristic.
