Mention the Netherlands, and most people think of brightly-colored tulips, gently-flowing canals, legal marijuana, and Rembrandt.
But there is an underside.
The U.S. State Department issued a travel warning Sept. 28, cautioning tourists about a potential terrorist threat in the country. The announcement came largely in response to an August attack at Amsterdam’s Central Station, in which two Americans were stabbed by a German Muslim extremist.
True, the Amsterdam attacker was not Dutch. But Europe’s permeable borders mean that nationality rarely matters; several of those involved in the November, 2015 Paris attacks, for instance, were Belgian.
Moreover, the country’s intelligence officials have been warning of an impending incident for some time, noting the sizable number of extremists throughout the country, along with 55 returnees from the Islamic State.
