If we be logically honest instead of being illogical and honest, then perhaps we can realize that we can't simply just go out and make something which we haven't made before.

We don't have any Fire and Forget ATGMs and OMTAs and UMTAS can make a hell of a lot of difference, here. Not to forget the lock on after launch feature.
