"the draft" which required all young men to be ready for military or other service. answer 1 channeling of a nation's entire resources into a war effort. answer 2 spreading of ideas to promote a certain cause or to damage an opposing cause. answer 3 agreement to end fighting in a war.

The correct answer is answer 1 " Channeling of a nation's entire resources into a war effort."

In order to have a successful war effort, countries must be able to:
- Get their affairs in order.
- Have sufficient technology/ammunition
- Have sufficient food/resources
- Have military personnel to serve.

In this case, drafting citizens into a war shows a country's commitment to the war effort. The US uses this strategy, especially during the Vietnam War in which thousands of young men between the ages of 18-25 are selected for military service.
