Help on how to decide on the info stated in body paragraphs for war comparison essay

Hello all, I am new to these forums. I have to write an essay "comparing and contrasting" LBJ's and Bush Jr's justifications for promoting their respective wars" (Vietnam War and War on Terror, respectively. I have all the information I need, I just need help on organizing it into body paragraphs. Can I get suggestions on how to organize it into three body paragraphs?

Introduction - What all wars has happened which included US in it. One liner on both wars. What you are going to discuss in subsequent paragraphs.

Para 1 - Similarity between two wars

Para 2 - Difference between two wars

Conclusion

This is my suggestion - Write one body para to educated the reader about LBJ's justifications. Use the second one to talk about Bush Jr's justifications. In the third para, present your analysis ( compare and contrast the two). Is this strictly 3 body paras or you can have more ? If so, you can have the third and fourth to talk about similarities and differences. Hope this is helpful :)
