I agree no immediate war
But As long as a hostile nation, much bigger , has the water blackmail option over you and has announced it, then you have the defining choice as a nation to sort it out or accept slow coercion future generations
Water is scarce, population is growing, temperature rising
Before the Gaza annihilation you had over a decade a whole host of strangulation tactics employed before the final act that made the population dependent and at Israels mercy, you are literally being told a possibility, things are cooking in the west flank
Sorting it out can and should also mean improving your own infrastructure, responding persistently and cleverly diplomatically ......and this is all underpinned and made credible with a very serious and credible military response and capability
It's not time for a gun alone, but a properly planned out civic society that abides by a social contract with the state, and each other
