NAP Breach?

[Ewierl]

This is precisely the sort of situation where Real Diplomacy comes into play. It's worming around the edges of what a NAP does (or doesn't) mean, eithjer interpretation could be seen as valid. All depends on whether or not you want war eventually/soon, how much you want to pressure vs. reassure your ally, etc.

Even if there's "technically" no breach of the NAP's letter, you'd be equally legitimate in denouncing it as a breach of the treaty's spirit.
