At the end of World War II, Russia wanted assurances that NATO would not shift eastward, threatening Russian territory. After the fall of the Soviet Union, however, Ukraine and other Eastern European nations became independent, removing the buffer zones between Russia and NATO. Romania, Bulgaria, Poland and the Baltics have all become NATO members, and Russia sees this as a security concern.

Two-and-a-half years after the U.S. pulled out of Iraq the country has crumbled into a bona-fide failed state, with Baghdad under siege by ISIS (jihadist militants from the Islamic State), who are having a run of Iraq, and some analysts now worry that ISIS will commit mass genocide against Iraq's Shi'a population if Baghdad falls. The war in Iraq started with Operation Shock and Awe but ended in a fizzle and, some would argue, in an epic exercise in human futility. 

Bertha believed passionately that an individual could indeed change the course of history and, for a brief shining moment, it seemed as if she actually might. In his book, Professor Dolmetsch describes a massive peace rally that Bertha staged in Vienna in 1898. She managed to secure Mark Twain as a speaker on this occasion, but the principal address was given by one Lt. Col. Manfred von Egidy, a Prussian officer who had been dismissed from the army for writing and circulating an antiwar pamphlet.

Modern realignments have altered the military landscape along with prospects of future conflicts which have shifted away from the type of heavy land battles that tanks are required for. As political and military realities shift and the historical presence of tanks as main combat tools is scaled back, the battle over the tanks has found a new frontier in Congress, concerning political posturing and defense budget cuts. 

With the exception of Mohamed Bouazizi, the Tunisian fruit vendor who set himself on fire and thus sparked what became known as the Arab Spring, self-immolation has by all accounts become a failed form of protest as an agent of change. Since Bouazizi, in fact, 150 more Tunisians have set themselves on fire in protest against the new government that took over after the downfall of Zine El-Abidine Ben Ali's secular dictatorship. 

In the mounting war of words North Korea is having with the United States and its allies, it’s easy to believe who the chief aggressor is. A bankrupt dictatorship more interested in arming itself than feeding its populace can hardly expect a sympathetic audience. Yet signals coming from inside the communist nation – via headlines, reporters, tourists and business people alike – are turning that picture on its head.
