Germans react angrily to the treaty

1. Germans were no aware of the situation in 1919. 
Germans were very mad at this because they were completely left out of treaty negotiations (which was going to happy even if they said they wanted to be there) and the punishments that they had received.  Especially because they had lost so much already and now they are getting blamed for the war plus losing land plus they have to pay reparations
2. War guilt and reparations
the Germans couldn't pay this reparations because it was so much and they have a bad economy because of the war. As well as the whole war was placed on their shoulders even though they did not start the war. Being the sole responsible for this great war crushed the Germans and made them even more mad.  
3. Disarmament
Disarmament made the Germans very mad because they wanted to have an army and everyone else could have an army except them. this also kept the Germans completely defenseless if an attach was carried out on them. this made them powerless to the whole world
4. German territories
German lost many territories which made them mad because many of the territories had German people and so this caused anger within Germany. also the strongest and most resourceful areas were taken from Germany crippling their economy  
5. Fourteen Points and League
The fourteen points made Germany mad because it encouraged Europeans to break away from their home countries in order to have a better government. Also the league of nations excluded Germany which made them very angry.
6. Double Standards?
Double standards made germany mad because whatever they did Britain would just do them selves and it would over shadow Germany causing there to be a double standard between the two countries .
