World War I completely changed the way wars were fought.
Trench warfare, which was the norm just a century ago was seen as an nonviable strategy.
Modern machines such as tanks and airplanes made trench warfare mostly about keeping ground and resulted in stalemates.
Also, it was the first time that modern tanks, planes and machine guns were being used for first time at such a large scale, resulting in an unprecedented level of death and carnage.

The three main objectives of the Constitution are:
1) It makes a national government which consists of the three branches, with checks and balances among them.
2) It divides power between states and the federal government.
3) It protects the liberties of the American people.
The technologies were only used to observe enemies but as their effectiveness became apparent, both sides started to dismantle what they were using. For example, they shot down the planes that they would see causing more death.
