Unlike certain other institutions, NATO is an alliance of separate sovereign countries. I thank the Minister for his strong support of NATO, but does he agree that we should follow the example of the frontline NATO states like Estonia and Poland, which recognise that the difference between deterring a hostile Russia and actually having to fight a war is the difference between spending 4% or 5% of GDP on defence, as we did in the 1980s, and 40% or 50% if, God forbid, we ever have to engage in open hostilities?
