Israel could use one, but only in limited ways.
Does any artillery have shells that are over a ton each? I really don't know, but I'm thinking not, so surely it adds more capability. I don't think missles from fighters have the impact. It would lack the precision though.
The speed is certaily equal to what else is out there. With a clean hull and engine, they have been recorded at over 33 knots. Since capital ships seem somewhat custom, the issue of having a dissimilar machinery seems minor. Factories often use older equiptment, so people can obviously learn.
But why would we give away a multi-billion dollar American platform? If they need a monitor, they can spend the billions we give them on one. Cost was not an issue brought up in the latest dust-up, nor was lack of firepower.
As a practical matter, it would insure that more civilians would be killed. That was an international issue. If a fighter can't get in the area to target a missle firing site before the crew moves on, I can't imagine a battleship would do any better.
In the modern world, the usage is limited anyways. They are big targets for missles.
