Be Careful of War

On my next try at Civ I realized that I needed a balance between expansion, argriculture, and military. I had this balance working extremely well for a long time and also I helped myself in keeping allies with the other dominant civilizations in the game and the most of the civilizations around me. These allies reall helped me, in that I knew where to keep most of my military troops, which are not the easiest to move around in the game. These allies also opened me up to m first chance to expand by force and establish a dominance in the game. Ceasar had attacked one of my biggest allies in Egypt, so I decided with my upgraded military I would wipe them out which I started to do very easily, since I had tanks and gunships and they had longbowmen. Then while I was attacking Ceasar, Mongolia declared war on me. Luckily I had left some troops in the city closest to Mongolia which I was able to start an attack, so I wasn't fighting on my own land, and protect my cities at the same time. At this point, I realized I had overlooked an essential part of the game that was hurting me. I realized that after declareing war I had been losing over 100 gold every turn. Luckily I had built up a huge supply of gold, but if this were not the case this overlooking could have been a huge mistake. This really translates into real life, because wars do cost a lot of money, and if a nation is defending itself they could lose a great deal of money, and also start to lose their land because they can't suport theri troops. This just shows that before you go to war make sure you have all the angles worked out.
