Iran getting Nukes will worsen the situation, it's like we'll have a new bully in the ME, don't take me wrong my Iranian friends, I'm just stating a fact, and tbh, Iran is nowhere near to making a Nuclear device, and it's a signatory to NPT. And even if Iran gets Nukes, it's not only Israel who should be worried about them, it's actually whole Muslim world, we would have KSA and Iran going crazy on each other, and we all know Saudis are gonna go for a Nuke for themselves as well.. And that's where bad time starts.. It's not that I'm against KSA or Iran getting their hands on Nukes, but I think they are still those 5 yeaar old children who would fight with each other.. For God's sake, we don't want a Nuclear confrontation between two Islamic Countries..
And about KSA having a Nuclear umbrella, well, there's reality to it..
Pakistan do have this agreement with them, I mean we all know it's not possible if KSA is under threat and Pakistan wont do anything, that's a common sense now..
Rather than having Nukes of your own, lets go for a bloc which serves Muslim countries' interest, then we can all have Nukes, like NATO countries do.
