my opinion on who is responsible for causing the war
Even though many people blame Serbia for the outbreak of WW1 I personally believe Germany and Austro-Hungary were the main countries responsible. I believe Germany played a main part in causing the war because they decided to expand their empire overseas which angered many other countries and caused tension between all of them. I also believe this because Germany had the power to halt the disaster that was about to strike in July 1914, by withdrawing its blank cheque offering to support the Austro-Hungarian invasion of Serbia. Germany also declared war on Russia and France pre-emptively and invading Belgium, which then brought Britain into the war. I believe Austro-Hungary also had a main part in causing the war because of its decision to use the assassination of Archduke Franz Ferdinand as an excuse to conquer and invade Serbia.
