The United States continued to help South Vietnam. In August 1964 the North Vietnamese attacked a U.S. warship in a waterway called the Gulf of Tonkin. Afterward the U.S. Congress gave President Lyndon B. Johnson the power to expand the U.S. role in the war.

In August 1974 the United States cut back its military aid to the south. The South Vietnamese army fell apart quickly after that. In 1975 the North Vietnamese launched a massive invasion of South Vietnam.

The Vietnam War had a huge cost in human lives. More than 1.3 million Vietnamese soldiers and about 58,000 U.S. troops were killed. More than 2 million civilians (people not fighting the war) also died.

In war zones, drones are used to target members of non-state organized armed groups that the U.S. is engaged in armed conflict with, such as ISIS in Iraq and Syria and al Qaeda and the Taliban in Afghanistan.

The cost per flight hour varies by type of drone, but the larger armed systems such as the Global Hawk cost up to $15,000 per hour. According to information obtained via a Freedom of Information Act request, construction of the drone base in Niger was projected to cost $100 million.

Drones have rapidly become one of the U.S. military’s primary weapons as U.S. counterterrorism policy has gravitated toward methods that are more secretive, more lethal, and more removed from the battlefield. Here’s what you need to know.

But the government’s secrecy around its use of lethal drones has concealed the real human toll of these attacks. According to the Bureau of Investigative Journalism, drone attacks in Afghanistan, Pakistan, Somalia, and Yemen have killed between 8,500 and 12,000 people, including as many as 1,700 civilians – 400 of whom were children. This is a conservative estimate of how many civilians have been killed, especially since who qualifies as a "combatant" is widely disputed. These figures also don’t include killings in Iraq, Libya, and other countries. 

For years, the American Friends Service Committee has joined other organizations in calling for a ban on drone warfare. The United States’ use of lethal drones has killed thousands of people – including hundreds of children – and displaced countless others. Instead of making the U.S. safer, drones have undermined efforts to end conflict and build stability and viable economies in countries around the world.

The U.S. government had a long history of racist treatment of Asian immigrants and their descendants. Laws severely restricted Asian immigration starting in the late 1800s.

Between 1942 and 1945, a total of 10 camps were opened, mainly in remote areas of the western states. The Japanese Americans who were detained in the camps lost their freedom, their civil liberties, their jobs, and in most cases their property as well. Most of them were U.S. citizens.

During World War II, the U.S. government forced some 120,000 Japanese Americans to leave their homes. They were moved to internment centers, or concentration camps, where they were confined for the rest of the war. The camps were officially called relocation centers.

Several years after the war, the Americans and Soviets had created even more powerful hydrogen bombs which could now be fired at long-range targets all over the world, using missiles.

Hiroshima and Nagasaki Atomic Bomb Background Before the war, many scientists had been investigating the possibility of generating energy and even weapons from the atom, the building block of the universe and everything that surrounds us. The famous scientist Albert Einstein represented these leading thinkers by writing to the American president Franklin Roosevelt in August 1939.(adsbygoogle = window.adsbygoogle || []).push({}); Franklin Roosevelt He told him about their ideas and the danger of the Nazis in Germany developing such a bomb for military use. Roosevelt responded by setting up a group of experts to develop the idea in the United States. The idea only really got going after the Japanese bombed the American Naval Base at Pearl Harbour in December 1941. Other countries also saw the appeal in having a very powerful weapon that would prevent their soldiers being killed in large numbers, as well as being able to stop enemies from making possible attacks on them. These countries included Germany, Japan, the United Kingdom and the Soviet Union. However, none of them were able to make the bomb before the Americans.if(typeof __ez_fad_position != 'undefined'){__ez_fad_position('div-gpt-ad-historyforkids_net-box-3-0')}; Between 1941 and 1945, the scientist, Robert Oppenheimer, led a group of experts on the Manhattan Project with the aim of making the world’s first atomic bomb. Robert Oppenheimer Many of the people on Oppenheimer’s team were scientists who had escaped Nazi Germany. They all worked at a special research site at Oak Ridge, Tennessee. The decision to use the bomb Throughout the war, Allied forces heavily bombed Japan killing hundreds of thousands of people. But the Japanese survived these attacks and were still very strong. They refused to surrender and so President Harry Truman thought about a possible invasion of the country. The Japanese army was huge and the President knew that he would lose hundreds of thousands of men, if he embarked on such a plan. So, in July 1945, Truman offered the Japanese the chance to surrender. He knew that the bomb had now been completed and effectively tested in the New Mexico desert and was ready for use.if(typeof __ez_fad_position != 'undefined'){__ez_fad_position('div-gpt-ad-historyforkids_net-medrectangle-3-0')}; The Japanese wanted to negotiate the conditions of surrender and refused to give in to the demands of the Allies. Hiroshima The Americans targeted Hiroshima because it had not yet been hit by their air raids. This meant that it would be a better testing ground to examine the effects of the atomic bomb over a particular area. Hiroshima also had an important military base. On the morning of the 6th of August 1945, Paul Tibbets flew an American B29 bomber plane, called ‘Enola Gay’, over the Japanese city of Hiroshima and dropped the bomb named ‘Little Boy’ at 08:16 am local time.if(typeof __ez_fad_position != 'undefined'){__ez_fad_position('div-gpt-ad-historyforkids_net-medrectangle-4-0')};if(typeof __ez_fad_position != 'undefined'){__ez_fad_position('div-gpt-ad-historyforkids_net-medrectangle-4-0_1')};if(typeof __ez_fad_position != 'undefined'){__ez_fad_position('div-gpt-ad-historyforkids_net-medrectangle-4-0_2')}; .medrectangle-4-multi-660{border:none !important;display:inline-block;float:left !important;line-height:0px;margin-bottom:15px !important;margin-left:20px !important;margin-right:10px !important;margin-top:15px !important;min-height:250px;min-width:300px;padding-bottom:20px !important;padding-top:20px !important;} The explosion was devastating and instantly wiped out the entire city. 140,000 people were killed at the time of the explosion and by the end of 1945. The intense heat of the blast led to fires throughout the city which continued for three days, making survival more difficult for those who were not killed in the initial explosion. B-29 bomber Enola Gay Nagasaki On the 9th of August, Charles Sweeney piloted a second mission on another B29 called Bockscar with the ‘Fat Man’ bomb, as it was known. The main target of the bomb was in fact another Japanese city, Kokura. Due to cloud and smoke over Kokura, visibility was poor and Japanese fighter planes were drawing near

of instability. In the wake of this instability, extremist movements such as Communism, Fascism, and National Socialism emerged.

The Holocaust was not a single event. It did not happen all at once. It was the result of circumstances and events, as well as individual decisions, played out over years. Key political, moral, and psychological lines were crossed until the Nazi leadership eventually set in motion the unimaginable—a concrete, systematic plan to annihilate all of Europe’s Jews.

Other physicians conducted unethical and cruel medical experiments, and determined in “selections” at killing centers which prisoners should live and which should die.

The members of the SS, the elite guard of the Nazi regime, were key players in the "Final Solution," the plan to murder the Jews of Europe. The head of the SS, Heinrich Himmler, and his subordinates, Reinhard Heydrich, Kurt Daluege, and others, established the SS and police state under Adolf Hitler and led the efforts to carry out the regime’s ideological agenda. Toward that end, the SS perpetrated countless acts of mass murder.

The victims were told they were to be taken to labor camps, but in reality, from 1942 onward, deportation meant transit to killing centers for most Jews.

The first concentration camps in Germany were established soon after Hitler's appointment as chancellor in January 1933. The Storm Troopers (SA) and the police established concentration camps to handle the masses of people arrested as alleged political opponents of the regime.

Jews have lived in Europe for more than two thousand years. The American Jewish Yearbook placed the total Jewish population of Europe at about 9.5 million in 1933. This number represented more than 60 percent of the world's Jewish population, which was estimated at 15.3 million. Most European Jews resided in eastern Europe, with about 5 1/2 million Jews living in Poland and the Soviet Union. Before the Nazi takeover of power in 1933, Europe had a dynamic and highly developed Jewish culture. In little more than a decade, most of Europe would be conquered, occupied, or annexed by Nazi Germany and most European Jews—two out of every three—would be dead.

They have produced evidence that Hanning was in Auschwitz during the Hungary Operation and is therefore directly implicated.

Hanning did not respond. 

It was also an opportunity for justice more than 70 years after the end of the war.

After a four-month trial, a former Auschwitz death camp guard has been convicted of aiding in the murder of 170,000 people. The former guard is now 94 years old and the trial is likely the last of its kind.
