In 1917, President Woodrow Wilson declared war against Germany, for the reason being that Germany had violated their pledge to stop the unrestricted warfare because they were sinking boats with innocent civilians on it, also because Germany had been attempting to have Mexico form an alliance with them just in case Germany and the United States were to go to war. After the war took place, though with all the death and destruction, good things had came out of the war as well. War always seems to speed up with new technology, while being under intense pressure for the obvious reasons, but for this specifically new weapons were made such as machine guns, tanks, and chemical weapons. Which is a good thing to have as many weapons as you can to fight against your enemy. It is always good to have as many people on your side of the battlefield as you can during war. That’s exactly what happened during and after world war one, France, Britain and Russia had joined allies with the United States. Lastly on another good note America’s power increased more than it already been slowly but surely becoming the world’s super power , making people think twice about going to war and more allies, it was worth it. World war 2 began September 1, 1993, though America did not enter until December 7, 1993, after Japan bomb the pearl harbor. America did not fight only one war during this period but two, right across the globe from each other. It’s to say that the war with Germany was the most horrific because of hitler killing the Jews which was around 60 million people. Many lives were lost during the 6 years but what came out of the rubble had been a few good things. One being that the war drastically changed the perspective on racial discrimination for that specific moment allowing all people of color and religion to work in the factories, participate in the war and other things that related to war work. Women began to slowly be accepted into society as equal beings and not second class beings. The women slowly but surely made their way up the ladder to work alongside men for the given time helping out on war work and building the ammunition and the bombs for they, the men in battle can use for their enemy. Antibiotics had been also developed during this time which was good because it lowered the mortality rates for the children and for the ill, this made it all worth it. In 1947 the Cold war began, the United States does not like communism so when the Domino effect theory came to the United States attention that if China was a communist country it will trickle to Korea which it did, then to Vietnam which it also did, then the surrounding countries will also fall victim of this the one party rule. When J.F.K was elected as president he later made a speech that said the following quote “… Pay any price, bear any burden , meet any hardship, support any friend, oppose any foe, in order to assure the survival and success of liberty.” which is said too may have been a direct stab at the Soviet Union. Though the United States and Soviet Union did not want to engage in a hot war because both had been making nuclear weapons and the thought of a nuclear war did not sound very appealing because they both would have lost everything they worked for. Which is lead to the proxy wars such as the Vietnam war, the Soviet war in Afghanistan, and the Korean war and well as a lot of others, it was not worth it.
