I think it could be all those things. I do think they are using water as a metaphor for something and a signal. Remember also PM Netanyahu pouring a nice cool glass of water out of a glass picture and telling the Iranian people that ‘the water is on the table.’
The current Iranian uprising started with water.
And, watch CA. They have a division question for November (beating the secessionist back).
And that the offer of water to the Iranians might be a catalyst for the uprising of the Iranian people.
