How did technology make world war 1 different from earlier wars?

Weapons in WW1 were being mass produced and of a greater quality than those of wars before. Barbed wire, airplanes, poisonous gas, submarines etc were introduced which revolutionized war today. Trench warfare was countered and is no longer used to fight.

Weapons are now being produced to counter Trench Warfare. The idea is to keep a strong defensive while creating weapons to at least try an offensive. The gas would settle in the low spots, forcing soldiers out of the trenches and out into the open.

Explanation:

trumans defeat to eisenhower in the 1948 elections was due to trumans approach and handling of the cold war and the war in korea. trumans approach to communism during the cold war was the principle reason for his defeat. eisenhowers reputation and name as the supreme allied commander in europe during world war two and his campaign slogan that he ''would go to korea if elected'' won him the presidency.
