Events in Israel/Gaza, Ukraine, and on the U.S.-Mexican border have captured our attention in recent months. Although they are unfolding in different parts of the globe, they have certain features in common.
First, of course, each vies to be singled out as the best example of man's inhumanity to man. Irredentist Russian nationalists in Ukraine have resorted (first) to an uprising against their government with Russian support and (second) to warfare against unarmed passenger aircraft. (Here, we might excuse the latter as just a tragic accident, had they confessed the deed and cooperated with international investigation. They have not.) Meanwhile, parents of children in Central America have made a lamentable decision to abandon and endanger their children by sending them north. A cadre of Muslim zealots began, and continues, a war that will kill lots of the very people they claim to be fighting for.
All these fomenters of trouble share both a sense of desperation, and a cynicism about using other people's lives to advance their own purposes.
It can also be argued that each of these crises arises from various past attempts to "correct" history. The state of Israel was created and imposed by WWII Allies with total disregard for the reality on the ground at the time, a reality that had itself been created by the Ottoman Empire. The American southwest was effectively stolen from Mexico (which in turn had stolen it from the native American inhabitants). The exactly boundaries of "Ukraine' as a national construct have never been clear, but Russia under Stalin defined them as a ploy to gain additional votes in the UN, including areas of very mixed ethnicity; and subsequently in the Soviet period, Russia encouraged the settlement of ethnic Russians in Ukrainian areas.
Land grabs and the migration of peoples are a part of the tapestry of history. Sometimes they form a new reality that lasts for centuries; sometimes they are less permanent. But History doesn't like to be "corrected." Those who attempt it can find themselves in difficulty.
