National Missile Defense

National missile defense is when a country tries to protect itself from other countries' missiles. It’s like playing a game of catch, but instead of a ball, it's a really big and dangerous bomb. A national missile defense system would try to intercept and destroy the enemy's missile before it hits its target.

Imagine playing with two different kinds of balls - a regular size ball and a huge beach ball. The regular size ball is easy to catch and throw, but the beach ball is very big and hard to catch. That's kind of what it's like for a missile defense system to stop an incoming missile. It's easier to stop smaller missiles, but it gets harder when the missiles get bigger and faster.

The goal of national missile defense is to protect countries from possible missile attacks from other countries. It involves having special weapons that can detect, track, and shoot down enemy missiles before they hit their targets. These weapons can be on the ground, in the air, or even in space.

Just like how you put your hand up to catch a ball, the missile defense system uses things like rockets, lasers or programs to try to stop the missile. It's kind of like playing dodgeball, but instead of dodging the ball, the defense system tries to hit it with a ball of its own.

National missile defense is important because it helps to prevent war and protect people. Nobody wants to be hit by a missile, so having a missile defense system can give countries the security they need to go about their daily lives without worrying about an attack from another country.
