Answer:
A way by which the government might respond to rising threats to national security through fiscal policy would be:
By Increasing the Military Spending
Explanation:
National security of a country may include the security of its institutions, economy, people and much more, but it is usually focused on military issues.
To combat these threats, a compulsory and immediate response force is required, which is usually considered to be the armed forces (which respond to threats and aggression) of that country . Therefore, increasing the military spending is one way to respond to threats to national security, because a larger military presence means greater ability to respond to and prevent these threats.
