This is how Israeli Land Ownership generally works, with "terms" and dates and land which is owned, only being owned for a fixed amount of time. Most countries have some sort of Eminent Domain, including yours, in fact, Australia is one of the worst in terms of not requiring fair compensation. The key is, to be able to handle the necessary paperwork. Ranting and rioting and thinking that because you are an Arab somehow the law does not apply to you, is counterproductive.
