Indeed, if Biden was using only battlefield deaths, he actually could have said more people died of covid-19 than in combat during all of America’s wars against foreign enemies. That’s because fewer than 500,000 died in battle if you add up every war from the Revolutionary War to the conflicts in Iraq and Afghanistan. (We’re obviously not counting the Civil War.)
Or if Biden had liked the sound of comparing covid-19 deaths to three wars, he would have been more on target if he had added together all deaths from World War II, the Korean War and the Vietnam War. That yields a total of 500,193.
Biden has to watch his math. I find the actual battlefield death counts to be more accurate. Others may differ.
