In the US, we depend on others to protect us, our jobs and economy as well as our borders;from illegals and armed countries. The forces, who are used in other countries to protect Americans from harm, are generally the US military. When they are injured or sick, they use the Veterans Administration health care system.
If they are injured so that they can not return to service, or work they may qualify for a percentage of a pension. So why do we do this? Because it’s ethical and moral, to care for those who cared for us. Help give the VA guidance and ability.
