Poll about the German defeat in WW1

My problematic was: Did the USA was the main cause of the defeat of Germany in WW1?
The answer: No, after good research I came to the conclusion that the British Blockade was the most important factor. If we analyze the other possible causes, we can notice that blockade worsen their situation. Lets analyse each possible answer.

The fighting and casualties had a massive impact on Germany, it was nearly impossible to win the war anymore and didn't have enough man to replace the casualties, however if we look at the final battle maps, we can notice the line is not inside Germany, its inside Belgium and France, it is therefore possible to think, especially with trench warfare, that the Germans could of held for longer.

The USA entry into the war did bolster french moral, however the American troops weren't in the war long enough to truly be effective in battle, they did replace Russia in the man department, however their most notable act was their political pressure on Berlin which is one of the cause of the Kaiser abdication.

The Abdication was caused by both the search for peace, which required the Kaiser gone, and the political unstability in the country, instability indirectly caused by the blockade. We can see the abdication as more of a requirement for peace than the cause of the defeat.

Finally, the Blockade. The blockade, that ran during the whole war and the longer it lasted the stronger it became, effectively starved the German Empire, the british effectively shutted down all importation except for sweden (far from enough for the Huge German Empire). Troops didn't get adequate clothes for the rough condition of the tranches, got smaller food ration than the Entente soldiers and lesser weapons, this caused great demoralisation in the German camp. Things were worse on the home front, people were being fed 1500 calories a day, people starved and so they stole to survive, it is estimated tha around 700 000 people died from direct starvation. Germans also didnt get any hygiene products, therefore diseases were rampant. This climate had a great part in creating the political instabilities that pushed the Kaiser out of Berlin.

Thoughts Ivan Kolev , and others?

The improving of morale was TREMENDOUSLY important, however. In 1917, a massive French mutiny on the Western Front resulted in a lack of men to fight in large sections of the front, and revolution in France similar to the revolution in Russia was not that far fetched before American troops arrived. Once the Americans arrived, it improved French and British morale because, unlike the British or French, we were naïve and enthusiastic once we entered.

While there is no doubt that the blockade and military defeats weakened Germany tremendously, the USA's entry into the war was the only thing preventing a German victory in the war. And here are the reasons:

1. The Germans launched the Ludendorff Offensive early because they wanted to knock France out of the war before American troops arrived. As a result of this, not as many troops were involved as there could be if it had been launched later on.

2. Following Russia's surrender, the Germans signed an agreement with the new Ukrainian government basically stating that the Ukraine would supply grain for the Germans and the Central Powers and in return would be protected by the Germans. This would have solved the food issue in Germany. The only reason they weren't able to do this was because the Germans launched their offensive earlier than they probably should have due to America's entry. Plus, by 1918, there were lots and lots of American troops on the Western Front and helped to really batter through the last German defenses in 1918.
