How did fighting on multiple fronts (in different places) affect the countries at war?

They Would Have To Pay Taxs For The War And Families Would Loose People That They Loved During The War. The Prices On Things Would Go Up And It Could Be Possible That There Could Be A Draft If They Loose To Many People. They Would Loose Land From The War And The Diffrent Countries Would Fight Over Land And Try To Conquer Land.
