The United States had entered the conflict in Vietnam as the world’s superpower following its decisive victory over the Axis powers in World War II, but left Vietnam with a humiliating defeat, shockingly high casualties, American public sharply divided and its leaders uncertain of what lay ahead in foreign policy. The nation’s longest and most debilitating war – the only war the U.S. ever lost, had far-reaching consequences and impact on most aspects of American life from the economy, culture to domestic politics and foreign policy – some of which continue to do so today.The Vietnam War damaged the U.S. economy severely. The U.S. had poured some $168 billion into the war, but the real cost of the conflict was its impact on the economy.
After a few truly good years during 1962 – 1965 when there was low inflation, almost full employment and a favorable balance of trade<span>, </span>President Lyndon B. Johnson, who succeeded President Kennedy after his assassination in 1963, declared a “War on Poverty” through his “Great Society” programs while escalating the war in Vietnam at the same time.
However, his decision to finance both “guns and butter” – a major war and the Great Society simultaneously, without a significant increase in taxes unleashed an acceleration of inflation peaking at a runaway double-digit in mid 1970s.
Not until 1969 did President Johnson decided to introduce a 10% income tax surcharge, which is considered by many economists “too little and too late” and in turn also slowed down the economy. It’s worth mentioning that Congress would not allow that “surcharge” to be implemented until President Johnson agreed to cut $6 billion from domestic spending on Great Society programs. Despite their relative success, Johnson could have undoubtedly spent more on these programs had he not had to pay for the war abroad, which Martin Luther King, Jr. had referred to as a “America’s tragic distraction” at the beginning of Johnson administration
Discovered that Earth rotated on an axis.
Aryabhata was a great astronomer and mathematician from the Classical Age of Mathematics. His discovery that the world rotated on an axis was contrary to the then-popular belief that the sky rotated. He also stated that the sun and the moon rotate around the Earth. He also calculated the positions of the planets and their periods of rotation around the Earth. He was very keen on epicycles, which is a geometric model to explain the variations in speed and direction of the planets.
The Battle of Ravenna, fought on 11 April 1512, was a major battle of the War of the League of Cambrai. It pitted forces of the Holy League against France and their Ferrarese allies. Ravenna was henceforth the capital of the Western Roman Empire until its dissolution in 476. As such, Ravenna was embellished with magnificent monuments. The city was also raised to the status of an archbishopric in 438.
