The UK needs to do more to secure our own defence in an insecure world. The government needs to improve our defences against incoming missiles and drones, by constructing a modern Iron dome or shield. Israel, the US and Ukraine have experience we can draw on.
We need to strengthen our surface fleet and our submarine capacity to protect our waters and the infrastructure they contain, and to help NATO keep open international sea lanes. Above all we need to expand our domestic weapons making capabilities and ensure we have title to essential technologies and designs so we could quickly scale up production should need arise.
The first task which the government still has not done is to draw up a list of capabilities we need to augment or create, with a timetable. Then we can work out a more accurate costing and determine a pattern of spend to speed their introduction. It is wrong to start with a debate about money before deciding what we need. When we know what we need we can best decide when we can afford it and deliver it.
I do not think we should plan to fight a war against Russia with land forces on the continent. We do not have anything like a big enough army and would need far more money and conscription to raise and train one. 800,000 Ukrainians bravely keep a Russian army of 1 million in check. ( there is a range of estimates and guesses but most agree each army is more than ten tines the size of the UK ‘s). We have just 75,000 committed to a world wide range of roles. As the last four years have shown there is no need for the UK to become involved in fighting Russia in Ukraine and no wish by most UK people to do so. The UK condemns the Russian invasion and the war crimes against civilians but has no wish to escalate this into a NATO war. As the US throughout has made clear it does not wish to go to war with Russia so NATO cannot go to war given US dominance in the alliance.Our forces usually operate by close cooperation with US forces and often rely on their cover.
Whilst the West sees the Ukraine war as Russian unprovoked aggression to grab back old USSR territory Russia sees this as a war of EU expansion, with the EU wanting to gain influence over Ukraine to stop Russian influence. President Trump wants a peace settlement as he has no intent to use US and NATO force to push back Russia. This encourages President Putin to demand tough terms, just as President Biden’s prevarications probably decided Putin to invade in the first place. The earlier failure of the West to respond forcefully to his annexation of Crimea would also have egged him on.
So the US leaves helping Ukraine to the EU as their problem given the plan for Ukraine to become a member. The US does not want Ukraine to join NATO as Russia wrongly sees that as a threat. The EU countries with the possible exception of Germany do insufficient to help with either money or arms.
The UK does not have a big enough army in peacetime to even help keep a future peace in Ukraine, let alone to join the fight.When we twice declared war on Germany and planned a land war on the continent we had to recruit a hugely increased army and turn our economy over to war production before we could win, and needed our US allies to help. Time to be realistic about what we can do. Definitely time to be more serious about putting in more force to defend these islands.
