in the modeling they compare 3 angles of rotation about the x, y, or z axis, and it is claimed that the one with maximum inertia and the one with minimum inertia are both stable, leaving only the axis with intermediate inertia subject to the dzhanibekov effect. for earth, it is claimed, the rotation is currently in the maximum direction and hence stable. but this is not necessarily true since the axial pole has an admitted procession, and the theory that it is only competing against 2 other axis not valid given the many bumpy gravitational oddities of planet earth that is a misshapen spheroid, and because of unpredictable changes due to water, ice, movement in the core, earthquakes, and being struck or influence by asteroids/meteors/etc. so to what extent rotation along the equator is actually maximum versus intermediate no body has told us yet. the fear of being 'alarmist' censors full information being discussed.
