The answer is primitive, since medical practices were not nearly as advanced as they are today.
President Wilson believed that they shouldn't be too harsh on Germany & the Central Power, and believed in the 14 points (that he wrote)
However, Clemenceau and Lloyd George believed that they should put heavy reparations on Germany for being part of the losing side (even though they technically didn't start the war), to pay for all the damage costs, etc.
This led to Germany printing more money, and as their money decreased in value, it led them to the "Great Depression", which saw the arising of Adolf Hitler to power. From there, Hitler blamed the past government for not being able to fight on, and tried to build up a military force (which was forbidden under the Treaty of Versailles). However, France & Britain did not stop him, which led him taking over Europe in the next few years
hope this helps
It means that the military works for the king and not for the people that it should protect. He refers to the King of Britain and the sentence means that he basically uses the army not to protect the people, but as his own personal army to fight wars against who he thinks is the enemy. Instead of military working to protect the people, the military does not have accountability with the people.
