With respect, it's not my "rationalisation ", but that of those who were in charge of running the Empire and the UK. Personally, I'm pretty much with Barnett; most of the Empire should have been dumped pre 1939 or immediately post 1945. But all of that is with hindsight. The mindset of both the Conservatives and Labour was Imperial; they had come of age at the height of Empire and were trapped by it, as many are now trapped by the outdated concept of the EU.And there it comes, the rationalisation for the clinging. Anyone with half a brain could see that Malaysia was going to become independent, as it indeed did in 1957. So how much profit did the UK make from that extra decade of ownership? Especially after deducting the costs of the Malayan Emergency, the Indonesian Confrontation, and all the other expenditures that basically related to defending the USAs newly acquired south-eastern empire from communism.
How much did the UK economy benefit from selling weapons to tinpot regimes compared to eg West Germany’s benefiting from selling VWs to the entire world? Basing not only your entire foreign policy but consequently your defence policy and armed forces structure around “but we need to keep the sheiks on board so we can sell them shiny toys” also seems rather counterproductive.
Again, after WW2 the UK was broke. It could not afford the costs of empire, especially since any remaining benefits of empire were effectively going to the US anyway. But instead of questioning every expenditure on the basis of “what direct benefit does this bring the UK” it seemed to fall by sheer force of habit into “this is what the imperial power does so we should do it” even though the imperial powers were now the US and USSR. Consequently IIRC UK defence spending was a higher % after WW2 than it was in 1913 during the “arms race” and most of UK Marshall Aid went on supporting the US in wars on the other side of the planet, at a time when the economy was desperately fragile and lacking in investment since before WW1. All money pulled out of the civilian economy and pissed away.
I mean, we have just had a big discussion in this thread on the impact of the Korean War. IMO the UK should have taken a policy decision that NATO was its sole comittment and sent only whatever token forces it could easily scrape up.
But they did think globally. The concept of selling shiny toys to the sheiks was not just that. It was selling military assistance both materiel and expertise. It was to keep the oil flowing and free from Soviet influence; oil rich states are not "tinpot", as was emphasised during the Oil Crisis of the 70s. The West could not risk that being a weapon to be used by the USSR. Indeed the USA specifically asked the Saudis to let it have oil to continue fighting in Vietnam. However the UK could not provide the protection to the sheiks that the USA could, so the sheiks very wisely went with the USA. That allowed the creation of the Petro-dollar whereby oil can only be bought with dollars. That has underpinned the US dollar and therefore the US economy for decades; without it the USA would be much weaker.
With regard to the Korean War, the USA feared it was the organised prelude to a general aggressive war by the Communist bloc; the UK did not really believe that. However as the only two significant Western military powers extant and members of the Security Council who voted to assist South Korea, the USA and Britain could not then refuse to do so. Both re-armed to counter the supposed general threat, which was illusory as is now apparent.
As previously stated, the view of some historians is that it was the inflation in the price of raw materials, caused by the massive US rearmament, which derailed the UK economic revival. In other words, it was the indirect effect of Korea, not the direct effect.
Also, UK leaders were not necessarily ignorant of the problem of military commitments. Macmillan said of Germany "we are protecting them while they steal our markets....." But recognising a problem does not give the capability to solve it.
