what is he deadliest war that the U.S took part in?

Question

like WW1 or iraq

Answer 1

Neither. The American civil war killed more Americans than any other war America has ever been involved in.

Answer 2

If you adjust for the population of the country at that time and remember that both sides were the same country it would be the civil war.
At least 618,000 Americans died in the Civil War, and some experts say the toll reached 700,000. The number that is most often quoted is 620,000. At any rate, these casualties exceed the nation's loss in all its other wars, from the Revolution through Vietnam.
The Union armies had from 2,500,000 to 2,750,000 men. Their losses, by the best estimates:

Battle deaths: 110,070
Disease, etc.: 250,152
Total 360,222

The Confederate strength, known less accurately because of missing records, was from 750,000 to 1,250,000. Its estimated losses:

Battle deaths: 94,000
Disease, etc.: 164,000
Total 258,000
