War costs money! Money is used to build (in Vietnam's case): Swift Boats (these boats were built in Louisiana); PBRs (Patrol Boat River, built in Washington state); Monitors; Alpha Boats (ASPB-Assault Support Patrol Boats; these boats were built in Oregon); M48 Patton tanks (built in Detroit); ammunition/rifles/machineguns built in various plants thru out the continent...etc. etc. Once the war is over...so's your job.

To most African Americans the Civil War was a way to become free from slavery. After the Civil War blacks would no longer have to be in slavery, and this is why many African Americans signed up to fight for the Union army. They found this war as an opportunity to have rights, and become a citizen. African Americans fought to show that they did have loyalty to the North.
