My Lords, in addition to the obvious need of Ukrainians for combat aircraft and munitions, in the present situation can we at least make sure, with our allies, that they obtain the kind of super-efficient anti-projectile and anti-missile system as seems to be available to the Israelis? Can we ensure that the same standards are provided to the Ukrainians? Their system is good, but clearly it could be better still, and should we not work on that?
