Hey Guys, Not sure where to post this so move it if its in the wrong section. I'm trying to understand all this so am a noob. Watching Mike Maloney because I find it easier to understand. In this video (https://www.youtube.com/watch?v=EdSq5H7awi8&t=3s) he talks about the 7 stages of empires. One of the stages he discusses, is about a country putting its military to use or going to war. Question I would like to know/understand (in this example) is why did America go to war? They were prosperous, did they need to get involved? I was thinking, had they not gotten involved their expenses wouldn't have gotten out of control and maybe they wouldn't have the problem they have right now.
