There has been war as long as man has been on Earth. Over time, war tactics, weapons, armor and even the soldier have changed. The main weapon that changed the battlefield was the use of chemicals to stun, immobilize or cause death. Chemical warfare is not a new form of warfare; it has existed since 400 BC, but even a powerful and versatile weapon has its drawbacks. Even nature always finds a way to fight in battle. The threat of a chemical attack haunts every country today. Extreme tension in the Middle East leaves the United States paralyzed over its supply of chemical weapons and nervous about what the future holds. Advances in chemistry have altered the warfare frontline from its introduction in ancient history to current conflicts, and will continue to evolve into more of a threat in the future. Chemistry has been used in warfare since ancient history. At that time, life and war were very simple. The battlefield looked different, had different rules, different weapons, and different armor. At the time of the Greek Spartans, the greatest warriors of the ancient world, they discovered that mixing copper and tin as they were smelted created a compound metal that was very hard and easy to produce. This new metal was Bronze (Grossman). Fights were usually fought with swords, bow and arrows, and any other weapons that could cause serious damage. After the discovery of bronze, the Spartans found ways to burn sulfur fumes to cause eye irritation, vomiting, and a feeling of delirium (Grossman). Chemical warfare evolved even more after the birth of Jesus Christ. In 256 AD, the Sasanian Persian Empire used toxic smoke against the Romans (Lussier). There were even cruder ways to spread death; 134...... middle of paper ......pons would be nuclear, chemical and biological. One nuclear bomb can destroy more than half of the United States. After the explosion, the affected area would have been contaminated with radiation and other toxic material (Lussier). It's scary to think that this could be a possibility! The best thing the “Allies” can do is destroy or steal their enemies’ “WOMDs” (weapons of mass destruction). Chemistry has played an important role in warfare since ancient history to the present day and will continue to impact future wars. The use of chemical warfare has evolved from mixing chemicals to form compounds useful in creating harder, more powerful weapons to gaseous chemicals used to kill thousands of individuals. While it is impossible to know the full extent of the future use of chemicals during warfare, it is obvious that the effects will be devastating for the entire world.
