Saying conspiracy implies, even if unintentionally, the idea of conspiracy theories, or fringe ideas. Whether or not, they're ultimately born out to be true.
Those type of diplomatic moves are far from unprecedented, and I would consider a US leak as a reasonable possibility here. I'm not saying it's most likely explanation, or even that I believe it's what happened, just that it's not a fringe possibility.
It would be funny if it ended up being like the discord leak again.
Just some dude in the DoD who wants to talk shit online lmao.
Still you might have a point. The president wouldn't want to ruin their relationship right as elections are happening, so deliberately leaking the plans to cause a delay would be a smart move. Though I can't imagine Netanyahu would care that much. I feel like he'd still go ahead with the plan even if Iran was able to get bonus prepare intel.
Netanyahu knows an attack and more conflict now helps Trump win, so maybe? Iran has been desperately trying to help Harris by hacking Trump, while Russia has been going the other way, so it's definitely possible.
