1. How did the buildup of militaries help lead to war?

It's like getting a new toy. When you get it all you want to do is use it and play with it. I feel like it's the same case for building up a military you have something new and improved so you want to use it and you will find any reason you have to use it, no matter how big or small it is.

Hope this helped c;
