> Poland with 10 credible nuclear weapons is enough to break the economic back of any country who attacks, so they won't attack. If you are in a situation where you are even seriously considering a nuclear strike, that means you are viewing a threat as existential, which completely undermines the economic argument. > This needs what you said before, second-strike capability. Either that or a fast enough response time…
> If you are in a situation where you are even seriously considering a nuclear strike, that means you are viewing a threat as existential, which completely undermines the economic argument. No, because it's not symmetric. Party A may be an existential threat to party B, party B can prevent that existential threat just by being sufficiently painful. B doesn't even have to be close to an existential threat to A for it…
Yep. I'm basing my stance on Poland's current defense strategy [0][1].
Furthermore, Poland's on track to outcompete Russia in rocket artillery and tanks, so it has day 1 capabilities that are comparable to a tactical nuclear strike minus the cost.
> No, because it's not symmetric
Yep. It isn't symmetric, but it doesn't matter, because crossing the nuclear launch threshold is enough to justify retaliatory strikes and counter-strikes - which is something a state which lacks a second strike or nuclear triad cannot deter against.
And the Kargil War in 1999 was proof enough that two states having nuclear weapons capabilities alone cannot deter a war.
