It seems that the deliberate (and of course, illegal) annexation of the four parts of Ukraine by Russia is extremely dangerous! If the Ukraine attempts to reintegrates these areas, Putin will claim that the fatherland is, with the help of the west, being attacked and he might well use ABC weapons in revenge. (A = atomic, B = biological and C = chemical). He is now trust so much into a corner, that he is losing mental control, and as a despot, he seems to have free rain to even press the red button = WWIIII, because the Americans will respond in kind. It is not uncommon for dictators (In the past) to use the burnt earth principles (Hitler, Stalin, etc.)
