Now, as in 1956, the America administration was distracted by three crises, hindering it from effectively leading the country.
Then, as now, center stage was taken by a crisis in the Middle East: the Anglo–French–Israeli seizure of the Suez Canal, after it had been nationalized by Egypt. The European crisis was the Hungarian effort to throw off the iron grip of the Soviet Union. The Hungarian people bravely attempted to free themselves from Soviet hegemony, AKA the Warsaw Pact. The third crisis was domestic, though the public of that time did not realize its severity: President Eisenhower had suffered a major heart attack. (A detailed analysis may be found in David A Nichols, Eisenhower 1956)
Today, political paralysis may stymie effective American leadership in the current Middle East and Ukraine conflicts. If that happens, Ukraine (and more of the former Soviet Union) may slid back under Russian control and the entire Middle East may dissolve into chaos and bloodshed.
