If Israel's wise men, such as Maimonides, spoke of kings' laws, they were referring to the messiah king and how he would rule the nation. Halacha does not, and cannot, consider the existence of a Jewish state that is not established as a result of the messiah's arrival.
Israel's most famous philosopher, Yishayahu Leibowitz, best expressed this notion when he said, "The entire biblical constitution that deals with the state and society...was never meant for realization in the historical reality, but was rather an ideal picture of the time of the messiah."
