Hey, if OP says this is how it's gonna be, then there ya go. (ya might try to find some wriggle room with an individual nation with some smooth diplo talk lol)
Last round SNAFU & LoSS basically said "if you dont spy my nukes, I wont spy yours & we wont use them". Dats fine as rules of engagement, and both parties honored it.
OP's declaration is fine. Rules of Engagement.
