<u>Explanation:</u></h2>
There were a lot of factors -- most were not what Schlieffen expected.
1. France wasn't that easy to conquer. It took longer than Schlieffen thought.
2. Belgium did not respond the way Schlieffen expected. They fought Germany.
3. Russia was more flexible that Schlieffen thought. They mobilized quicker and were much more adept at using their forces.
4. In all, Schlieffen made plans that were inflexible and did not account for the way wars are actually fought.
The colonies were the first in history to declare a completely democratic republic, just before the French did it in the French revolution. Their fight against the monarchy and enlightenment ideals. The American revolution showed that it was possible to stand up to tyranny and inspired many nations in Europe to do the same, just like France did.
1. They believed that they completely relied on them for all resources and support
2.They did not have a strong army really
3. There were a lot of loyalists among the colonists
