Well, yes, I must admit that there is a lot of defensiveness when we mention another aircraft that might be seen as a competitor. F-15SE is a very different platform. I certainly have never proposed F-15 as an alternative in any theatre apart from ROK, and I'm only posting about it in that context to answer questions or explain what I know about it. I'm certainly not pushing it.
That said, I do wonder why a handful of folks here see the need to push the F-35 so hard as the solution to every region's needs.
