Acquiring nukes seems like the best way for any country to protect themselves against outside interference.
We know that as soon as Gaddafi decommissioned his nukes, Libya was targeted and invaded. If Iraq actually did have nukes, the USA wouldn't have been so brazen to invade.
China, Russia, and North Korea's acquisitions of nukes are also some of the main reasons why they are not easy targets for direct US invasion.
If Iran had nukes, it would drastically limit Israel's ability to indiscriminately attack Iranian assets.
Western policies against nuclear proliferation always seem to target the countries that need them the most to ensure national sovereignty, and never refer to their own nukes.
For example, they always fearmonger about "rogue states" like North Korea getting nukes, while being perfectly okay with Israel's own nukes. It might be best if these policies are ignored entirely.
You just answered your own question. Fuck the imperialists and fuck their "non-proliferation" hypocrisy. Why are they allowed nukes while other smaller countries are not? It's time to start ignoring them and their attempts to impose rules on the rest of the world that they themselves don't abide by.
