Israel doesn't seem to have any problem with gays in the military. Maybe you should refine it to "highly militarised nationalist states which don't really need the military", so that they can afford to kick gays out. Any figures for whether gays were more tolerated in the U.S. military when they had conscription? I remember (from the early 80s) fellow students describing  the tricks people used in the U.S. to try to convince the army that they were gay...
