This is your theory? This is the series of events you are imagining.
1. Iran starts enriching uranium for a nuke more or less after the invasion of Iraq. There might have been some halting efforts before that, but they ramped it up because they realized that it was the only way to guarantee they won't be invaded next.
2. Iran gives up its weapon enrichment program in favor of a diplomatic solution that involved trying to a quasi-peaceful foreign policy.
3. Trump rips up the deal, and Iran starts enriching more. They especially start enriching more when he returns to office.
4. All in all, Iran has spent tens of billions of dollars making a nuke for self-defense. It's taken two decades at least. It's been their primary domestic weapons program.
5. But instead of keeping it, they are going to gift this device -- for which they have paid so much in blood and treasure -- to Hamas, with the expectation that Hamas will use it offensively against Israel.
6. They are going to do this despite the fact that smuggling a nuclear weapon is exceedingly difficult for a number of reasons, and if they get caught, everything they have done will be for naught;
7. They are going to do this even though the use of the bomb by Hamas would be the end of Iran.
8. They are going to do this even though Hamas has no way of deploying it. Nuclear bombs are considerably less effective if detonated at ground level. So it would not be nearly as devastating as people might think, but Iran is going ahead with this plan. Also, Hamas could get caught with the bomb, as it's quite different than giving some dynamite or an AK to barely trained fighters.
9. Hamas will do this even though it risks destroying the holy land for which Hamas is fighting. Not only would the holy grounds be destroyed; the surrounding area will be more or less unlivable.
10. This is going to happen even though the purpose of the Iranian proxies is to create the cheapest, most expendable fighting force possible. That's why they used suicide bombing. It costs almost nothing to put a small bomb in a backpack of some young man who climbs aboard a bus and detonates it. It requires no training. It requires no money. But now, having nurtured these proxies, Iran is going to hand them tens of billions of dollars worth of weaponry.
And this line of reasoning is how you justify genocide? This is why people think you are racist. What you are saying to justify mass starvation is something that makes no sense at all. Small children would scoff at this. Skeletor had more sensible schemes. Maybe you are just this stupid, but more likely, you just do not care (or celebrate) what is happening to people you do not care about at all.
