similar ee's

hey!! i started working on my ee during the summer but now i see that mine is very similar to another that ive seen online. I am doing a history ee and i picked a fairly common topic (the reasoning for bombing nagasaki/hiroshima). im doing this by analyzing all the other possibile ways the us couldve fought japan and then comparing it with the way they went about it. I found a very similar ee on a discord server w around 300k members pinned as an exemplar ee. lots of our facts are similar but the historiography is different and sources are also different. is this going to be an issue for plagiarism?
