The correct answer is A. The organizational structure of the United Nations, namely consensus voting in the security council, makes it incapable of preventing war between major powers. The United States should propose the United Nations be given the ability to prevent war(s) in the future.
Explanation:
In a persuasive speech that aims at convincing the audience about a certain idea or inviting the audience to take a certain action, the thesis statement refers to the main claim that guides the speech or the idea the speaker wants to convince the audience about. Because of this, a strong and effective thesis statement should express the position of the author but also provide in a concise way the reason or reasons that support this position.
Considering this, the best option for a thesis statement in this case is A. "The organizational structure of the United Nations, namely consensus voting in the security council...", because this statement clearly summarizes the position of the author, but also provides the reason behind it which is the incapability for preventing war of the United Nations as a reason to take action to change the way decisions are taken in the security council.
