The second video is pretty good.
He missed a few though like the tri-border region between Switzerland, Austria and Germany along Lake Constance. Complications along this border mean that Lake Constance is unclaimed by all three countries.
And regarding the Nederland-Belgium border: Frankly Belgium is a fake country, just like some other countries in Europe (like Switzerland, Austria both German nations, Belarus, Ukraine both Russian nations and several other little countries like Malta, San Marino, Liechtenstein, Luxembourg). I think they were created to act as buffer nations between bigger nations, kinda like the buffer nations of Nepal, Mongolia, Canada(
)etc.
