There is nothing strange that F-15 boys are worried and complaining about ET's effectivness and are expressing that, because they really should worry.
There is nothing starnge that they are completely blind to that "AMRAAM being UBER missile" issue.
I guess these two lines reflect the nature of the man pretty well.
BTW, you can see that I'm prone to act in a same fashion - I'm a MiG boy and I'm telling that - AMRAAMs are UBER and ETs on the other hand are just good.
You can never come up to a single and foremost truth unless it is backed up and implied by the direct usage of force.
