I don't think so. Jews are to return to their land (Israel, Judea) and they are not to be expelled. However, if we don't follow the law, the Moshiack will not come gloriously, but instead in what is called a natural manner and that may not be very pleasant. Such as what is going on right now.
What part of "lest the land vomit you out when you make it unclean, as it vomited out the nation that was before you" seemed ambiguous to you?
