Pretty much the same generals using the same tactics with just more effective weapons. A higher body count quicker.It changes the dynamics certainly and brings up some questions:
How would Franz Ferdinand’s murder will be handled with a Germany where Wilhelm is not willing to risk war with a Britain with Victoria at the helm? Does Victoria try to mediate?
What happens after Victoria dies? Would Wilhelm start to become hostile towards Britain or would George V be able to manage him?
If World War I is delayed until the 20s as a result of Victoria living longer, how would a World War I in the 20s be different?
