Political Philosophy on Retreating from a Nation's Lands
Jean Bodin is one of the greatest early modern political philosophers. He and another political philosopher, Claude de Seyssel, state specifically that a king must not give away the domain --the territory-- of the state.
Claude de Seyssel, in his Grand'Monarchie de France (1519) "... analyzes the triple restraint on the royal will: religion..., justice, which provides for the independence of the judges, and 'civilization,'" that is, the body of customary law and morality of the state, "or respect for fundamental customs, which prevents the King from giving away his domain." [= qui empêche le Roi d'aliéner son domaine] p17
Jean Bodin wrote in The Republic (1575):
"...the King cannot go against divine and human laws. He cannot break the fundamental laws, nor give away the domain of the state" [= ni aliéner le domaine de l'Etat] p27

On the related issue of disobedience to the will of the Sharon-Peres regime, two other early modern political theorists affirm:
"...the obedience due to the sovereign is only legitimate to the extent that he makes his actions conform to the supreme interest of the nation."

[Readers will note that the recent Israel Supreme Court decision on the matter is not taken seriously as a legal or judicial decision, since this court is commonly viewed with disdain, almost as much as the highly politicized and prejudiced "International Court of Justice" at the Hague, many or most of the members of which are appointed by tyrannical states. The Israeli Supreme Court nearly always takes the side of hostile foreign powers on matters of state and diplomatic issues.]
