I want to talk about the changes of the wars that had passed away between modern time's wars.

First, the weapons have changed a lot. In the old days, the soldiers sued sword or bows like those things, but nowdays, soldiers are using guns or bombs. Or some countries even used the nuclear bomb. Just like the thing that U.S. did to Japan. In the old day, they also used the bombs like in the Japanese Invasion, our patriots and freedom fighters used small bombs. But now, the technology had improved so now its so big.

Second, the soldier's uniforms have changed, too. In the ancient times, some soldiers didn't protect their legs and arms with the armor. So I think maybe many of them can died because of their Achilles tendon. It can be their mistakes, though. Now soldiers protect their body well with their armors.

Personally, I think doing the war, it has both advantages and disadvantages. For the disadvantages, the war kill so many people, and some of the countries made the other countries into their colony. I think it is a very bad thing to do. But on the other hand, it can also develop the tecnologies like, how we can protect our citizens well than before. And mayber some of the countries can give the science technology to people in their colony. But I want war to finish quickly. I make so many people horrible and depressed.

Thank you for listening to my presentation.
