It's just handbags at the moment.
The good news about history is it shows us examples of what not to do.
Plus, the war began because of a random tangential act (the assassination) that triggered a unique chain of dominoes that ended with a war almost by accident.
So if we are looking at something similar, we'd first need to ignore the precedent and then we'd also need a random chain of events to lead towards war by accident.
One thing this means is that the history doesn't make a reliable prediction for the future.
