Answer:
The progress made by the soldiers has more impact than words.
Step-by-step explanation:
People might not talk about or remember what happened, but the actions of the soldiers will cause significant impacts on their lives even if they don't realize it. It's quite the contrary of speeches meaning more than actions. It also doesn't mean that the world doesn't care about the soldiers, but that they won't notice it as much as they'll notice the changes caused by their actions.
