Here's the thing : If we didn't have a bunch of grandstanding pricks for politicians, we wouldn't need a massive full time army. Or at least not one anywhere near as big as we do. Look at the size of the armed forces the Scandinavians have. They're pretty much our geopolitical equivalent these days. The Swedish army is half the size ours. The Danish army is one twentieth.
It's only because our eejit politicians feel like sending them to every godforsaken dustbowl on earth in the name of 'The War on Terror' and some rabid desire to maintain a seat on the UN Security council that we pour tens of billions of pounds a year into an armed forces that, if we actually used them in a rational and reasonable way, we would only need a fraction of.
I'm not saying get rid. But the bare fact is we simply don't have the notion of the entire soviet army heading over the Rhine at short notice any more. We simply don't need a massive standing force. The notion of using reserves backing up a small highly trained cadre of full time soldiers is actually a really good one. It fits what we actually need to do and it fits the amount of money we should actually be dedicating to our military capability. But what we get is some bizarre notion that reducing troop numbers is somehow an affront to our national identity. It is a load of genitals.
What is an affront to our national identity is closing hospitals and libraries and privatising the NHS while we spend £25billion building a ballistic missile submarine fleet we will never, ever use.
