You are saying they have a weapon that let's them bend space time but incredulous that I would imply they should use it in the past? That argument isn't even internally consistent. Why can't they use it in the past if that is what you say it does?

That wasn't what I said though. I was practicing reasoning by analogy. You say they have developed a new superweapon that only they have. We can imagine what that looks like by looking at history for past times when that happened, nuclear bombs. This doesn't look like that at all for a variety of reasons.
