Defense industry

The defense industry is like a big store that sells toys to keep countries safe. Countries need to have ways to protect themselves in case someone tries to hurt them or take their things.

So, the defense industry makes lots of different things like guns, tanks, airplanes, and ships to help protect a country. These things are made to be very strong and powerful so that they can keep the people who live in that country safe.

Sometimes, different countries don't always get along, and they might need to fight to protect themselves. And just like how you play with toy soldiers and toy tanks to have pretend battles, countries will use the things the defense industry makes to have real battles if they need to.

But, the defense industry doesn't just make things that go bang and boom. They also make things like spy gadgets and cyber-security tools to help keep secrets safe and prevent bad people from trying to harm the country in other ways.

So, overall, the defense industry is like a big store that sells toys to keep countries safe and protect their secrets.
