Spoiler for panzerfaust:

I am assuming you are referring to the battle in the dragon's nest. The reason they didn't work was because the dark elves using them did not pull the nosecone tip out which converts them from standard HE to AT rounds. So the dragon was getting hit by splat explosives rather then penetrative explosions. Itami made a point of telling them this before they went in but they panicked and ignored him when he tried to remind them during the attack.

Spoiler for nukes:

I think he meant the USA.

And that seems unlikely. 1) Unless the LN readers tell me, Japan still have not granted the Gate access rights to any foreign power. 2) The security before and beyond the Gate is likely so tight that Japan is not going to take the chance to let Americans somehow smuggle a nuke beyond the gate.
