Initial forecast: the Venezuelan regime has destroyed every attempt by the opposition to challenge Maduro as a presidential candidate (https://www.americasquarterly.org/article/maduro-gets-his-wish-a-divided-venezuelan-opposition/).
Besides, international sanctions have had little effect in Maduro's stability within Venezuela. And due to his age, incapacitation by illness is very unlikely.
Why do you think you're right?
Initial forecast: the chances of such an event are particularly high for the upcoming weeks as Israel has effectively made a strike on Iranian soil, which had been unprecedented after years of attacks by proxies. Still, I believe a negative resolution is more likely, as these key facilities will be more protected as the risk is higher.
Why might you be wrong?
However, an attack to an Iranian facility of this kind can be used to justify escalating a war. This could serve Iranian interests.
