Following a popular post on Andorra in WWI, I decided to check my country's history after WWII. I know Nazi-Germany surrendered unconditionally on 4 May 1945, but I simply cannot find a peace treaty between our countries. Likely the same thing goes for many other (former) states that were at war with Germany. Does that mean that we are still - technically - at war?
We're at peace; The Netherlands and West-Germany (the BRD) signed a treaty in 1960 to settle all remaining points of conflict as a result of the war, notably with regard to reparations and border disputes. The BRD paid the Netherlands 280 million D-Mark in reparations, the Netherlands agreed to a number of border corrections and returned the towns of Elten and Tudderen to German control in 1963. An interesting side effect of the return of Elten to Germany was that it made a bunch of dairy and coffee traders very rich; on the night before it was returned to German control, they parked trucks full of butter in the town, which found themselves in Germany the next day without having to pay the at the time rather high import tariffs.
