the germans thought the treaty was diktat and was forced upon them. many wanted to reject it but had to accept it otherwise they had to continue fighting. they also hated the politicians who signed the treaty, named them November Criminals. you can write about the resistance to the occupation but that is really about weimar republic and is after treaty, like 1923
do you have any other examples of actions they took in response to the treaty other than the ruhr?
they believe that they were not responsible for the war. that's it really (at least from what i know)
