Perhaps rather than giving away other countries territory, you might like to return the Netherlands to Spain and see how well that works first?
I think you would agree there would be some major issues.
Well, the concept of handing the Falklands over to Argentina has similar issues......after all the Falklands were never part of Argentine territory. However the Dutch states were very definitely part of Spain, and some would argue still should be: you could argue that Holland is a renegade province of Spain, and that it should be returned to rightful Spanish rule
