Russia's war upon Ukraine should remind us that violent international conflicts not only persist, but constitute a plague upon the world.  Even so, there are practical ways to reduce international violence, notably through bolstering institutions of global governance.

Even international alliances can unravel when nations confront the insanity of a nuclear holocaust.  This is what happened recently when the Russian government threatened Ukraine and other nations with nuclear war, only to be rebuffed by its Chinese ally.  Much the same thing happened in the late 1950s and early 1960s, when, ironically, the role of the two governments was reversed.  These incidents demonstrate not only that nuclear deterrence is unstable, but that, while nuclear weapons exist, the world remains in peril.

Today, we're once more enmeshed in the dire situation so starkly revealed in August 1945, with the atomic bombing of Japan.  While nuclear weapons exist, any war can turn into a nuclear holocaust.  Unless the people of all nations, recognizing the peril of universal death, demand the establishment of an international organization capable of enforcing policies of disarmament and peace, then, sooner or later, the time will come to say "bye-bye world."

The Russian war in Ukraine provides us with yet another opportunity to consider what might be done to end the primitive and immensely destructive behavior that has characterized so much of human history.  Against a backdrop of thousands of years of bloody wars and the ever-present danger of a nuclear holocaust, it is time to dispense with international anarchy and create a governed world.

Donald Trump's illegal retention of classified U.S. government records reminded me that, in my capacity as a scholarly writer of international history, I have been reading these kinds of sensitive official files -- and learning from them -- for decades.  My research in U.S., British, Soviet, and East German records not only unearthed a good deal of information about great power behavior during the Cold War but, also, taught me how zealously governments guard their secrets.  In this context, it's possible that Trump's decision to hold onto classified files reflects a desire to withhold evidence of his own administration's extraordinary record of duplicity and malfeasance.

The Wagner Group, a shadowy Russian private company working hand-in-glove with the Russian government, has recently emerged as a major player in the thriving mercenary business.  It commenced operations by providing the military muscle for pro-Russian separatists in eastern Ukraine during 2014.  Since then, its thousands of armed men have brought widespread death, torture, and rape to Syria, the Central African Republic, Libya, Mali,  Mozambique, and Sudan.
