The Dutch absolutely should NOT follow suit. You guys stole our (Romanian) golden helmet when we sent it to a museum in the Netherlands[1] because you don't have any armed guards at museums.
Maybe send your gold to a country that actually protects priceless things, like the UK.
The UK under Gordon Brown foolishly sold off most of its gold reserves. If they had kept thrm, they would be worth £40B more today, or 10 times what it was sold for.
There is already arbitrary tariff. At this point, it is better to trade with other countries instead of chasing the US. Let the American citizen pay their tariff, their loss.
I wouldn’t worry too much about those threats. This administration is so erratic that you may see those same threats made against you for any other reason down the line even if you keep it put.
