IIRC, the standard doctrine is for the US to retain Command and Control until the nukes are released to the Theater Commanders Command but NEVER Control. The US & etc. keep their toys firmly in their mitts.
It is my understanding Turkey and Pakistan are BFF and we know Pakistan has nukes so I think it's safe to projection, with a high degree of certainty, if Turkey and Israel start slugging it out Pakistan won't stand by and let Israel blackmail 'em nuclear strategic wise.
H'mmmm.
Just about anyway I play it, Israel's nuclear forces will be countered through our good old friend MAD.
