Question

which sentence would be the best thesis statement for an argumentative essay supporting american use of the atomic bomb? harry trumans difficult decision to use atomic bombs against japan ended the war, saved lives, and secured a lasting peace. on august 6, 1945, the us air force dropped an atomic bomb on hiroshima, japan, killing more than 70,000 people. many scientists, including albert einstein, opposed the development and use of further nuclear weapons. i think president truman was right to drop an atomic bomb on hiroshima because i would have made the same decision.

Explanation:

A thesis statement for an argumentative essay should present a clear, debatable claim. The first option presents a claim that Truman's decision had positive outcomes (ended war, saved lives, secured peace) which can be argued for or against. The second option is a factual statement (about the bombing and casualties), not a thesis. The third option is about opposition to nuclear weapons (opposite of supporting use). The fourth option is a personal opinion without a broader, argument - worthy claim (just “I think” without a more general stance).

Answer:

Harry Truman's difficult decision to use atomic bombs against Japan ended the war, saved lives, and secured a lasting peace.
