If we want to remove the medina aspect of this topic, the question is, do we have a right to put our lives in danger to move to Eretz Yisroel and more specifically to Yehuda and Shomron? The problem with this question is that it is already assuming our lives are in danger in EY and the “proof” is that it is more dangerous than America.
Whether that’s true or not seems irrelevant to the halachic topic at hand. We don’t define sakana by comparing it other similar actions. There is an objective definition to sakana, and if living in EY meets that definition, then we have a serious question. If not, then we don’t, regardless of how much safer America may be.
