The entry of the US into the war proved devastating both for the Vietnamese and the Americans. This phase of struggle with the US from 1965 to 1972 was too brutal. Thousands of US troops arrived equipped with heavy weapons and tanks and backed by the most powerful bombers of the time, i.e. B52s. The widespread attacks and the use of chemical weapons like Napalm, Agent Orange, and phosphorous bombs destroyed many villages and decimated jungles. Thousands of soldiers lost their lives. Countless civilians met the same fate.
The tonnage of bombs, including chemical arms, used by the US in Vietnam exceeds that was used throughout the Second World War. This is the reason why some historians consider this war more brutal than the Second World War.
