I see. And how does that differentiate you from the nice men from ISIS who think the same way?
Here is how. During late WWII after Okinawa, the largest loss of life in battle, Truman faced an important decision:
How to finish this war, with the least loss of lives on both sides, going forward?
He received estimates for BOTH US military personnel, plus Japanese, considering how they behaved on the island battles.
He decided the use of atomic boms to bring about an immediate halt to the war, would result in the FEWEST deaths.
He made an humanitarian decision, and dropped two atomic bombs, killing just 200,000 or less.
That compared very favorably to predictions of how many Japanese would die if it dragged on, and most important US lives to.
You truly owe it to yourself, to learn about this historic episode in history.
If you still fail to understand, then you are probably so naïve, that you will never understand.
https://en.wikipedia.org/wiki/Atomic_bombings_of_Hiroshima_and_Nagasaki* As an historical point, the US, Britain, Russia, Germany and Japan were ALL trying to develop atomic bombs.
So if you possess some notion that war can be waged with delicacy, wake up.
