Germany set to vote on historic increase in defence spending

What happens today, here in Berlin, will impact the entire future of Europes defence and its ongoing support for Ukraine.

Germanys Parliament, the Bundestag, is voting on whether to take the brakes off defence spending. This could pave the way for a massive uplift in military investment just as Russia makes gains in Ukraine and Washington signals that Europe can no longer rely on US protection.

"This vote in the Bundestag is absolutely crucial," says Prof Monika Schnitzer, who chairs Germanys Council of Economic Experts.

"After the Munich Security Conference, then the Trump-Zelensky row, Europe got a wake-up call. For the first time Europeans may not be able to rely on Washington. A lot of people had sleepless nights after that."

"The outlook for European defence spending hinges on developments in Germany, as the holder of the regions largest defence budget," agrees Dr Fenella McGerty, senior fellow for defence economics at the London-based International Institute for Strategic Studies.

Defence spending in Germany rose by 23.2% last year, helping to drive a record 11.7% rise in European defence outlay.

"The remarkable initiatives announced in Germany are key to enabling further growth," adds Dr McGerty.

"Without them, any progress made on strengthening Germanys military capability may have stalled."

Germanys incoming new Chancellor, Friedrich Merz, is in a race against time.

The new parliament convenes on 25 March and not everyone is in favour of all this money being spent, especially on defence.

Both the far-right AfD party and the far-left Linke have vowed to oppose it. The vote needs two-thirds in favour to go through, so Merz has a better chance of this happening today, under the existing (old) parliament. It then needs to be approved by Germanys upper house.

Meanwhile Europe is still coming to terms with the shock of announcements coming from the Trump administration.

At last months Munich Security Conference I watched as delegates sat open-mouthed listening to US Vice-President JD Vances blistering attack on Europes policies on migration and free speech.

This was preceded days earlier by US Defence Secretary Pete Hegseth telling Nato members that Americas 80-year-long defensive umbrella for Europe should no longer be taken for granted.

Defence strategists in Europe are already planning for the unthinkable: a semi-victorious Russia making gains in Ukraine, then rebuilding its army and threatening Natos eastern members, such as the Baltic states, within three years or less.

This, at a time when the US commitment to Europes defence is looking extremely shaky. President Trump is being urged by some in his circle to pull US troops out of Europe and even to withdraw from Nato altogether.

There is talk of France extending its national nuclear deterrent to cover other European nations.

Meanwhile, most European governments are under pressure to raise defence spending after years of cuts.

The British Army has now shrunk to its smallest size since the Napoleonic Wars, over 200 years ago, and experts predict it would run out of ammunition within two weeks of fighting a full-scale conventional war in Europe.

Germany has long been cautious about defence spending, not just for historical reasons dating back to 1945, but also due to the global debt crisis of 2009.

Which brings us back to todays crucial vote in the Bundestag. It is not just about defence. One part is about freeing up €500bn (£420bn) for German infrastructure – fixing things like bridges and roads, but also to pay for climate change measures, something the Green Party insisted on.

The other part is about removing the restrictions in the constitution on borrowing that could, in theory, free up unlimited billions of euros for defence spending, both for Germanys armed forces and for a pan-European defence fund. On 4 March European Commission President Ursula Von der Leyen announced plans for an €800bn defence fund called The ReArm Europe Fund.

The proposal being voted on in Berlin is that any spending on defence that amounts to more than 1% of Germanys GDP (national wealth) would no longer be subject to a limit on borrowing. Until now this debt ceiling has been fixed at 0.35 pct of GDP.

Other countries will be watching closely to see if this proposal passes. If it does not, then the EU Commissions ReArm Europe project could be off to a shaky start.

The challenge today for Europes security is a stark one. If the US no longer has its back, or at the very least cannot be relied upon to come to Europes defence, then what does the continent need to do to fill the gap?

Lets start with the numbers. According to the Kiel Institute, which meticulously tracks these things, Europe spends just 0.1% of its wealth on helping to defend Ukraine, while the US has been spending 0.15%.

"That means," says the Kiel Institutes Giuseppe Irto, "that if Europe is to make up the shortfall then it needs to double its contribution to 0.21%."

But regardless of what happens today in Berlin this is not just about money.

Many of the most sought-after weapons in Ukraines armoury have come from the US, like Patriot air defence and long-range artillery systems like Himars. The Kiel Institute puts the proportion of Ukraines rocket artillery at 86% coming from the US, with 82% of its howitzer ammunition also being US-sourced.

Then there is the whole question of US intelligence aid for Kyiv, much of it derived from satellites and geospatial imagery. If Washington were to permanently switch that off, then Ukrainian forces risk being partially blinded.

If Americas nuclear arsenal is taken out of the equation then there is a massive disparity between Russias 5,000-plus warheads and the combined total of Britain and Frances nukes which amount to less than a tenth of that. But that still theoretically leaves enough to act as a nuclear deterrent.

When it comes to "conventional", ie. non-nuclear arms, Western defence chiefs are fond of saying that Natos combined forces are superior to Russias.

Maybe, but if there is one glaring lesson to come out of the Ukraine war it is that "mass" matters. Russias army may be of poor quality but President Putin has been able to throw such huge numbers of men, drones, shells and missiles at Ukraines front lines that the Russians are inexorably advancing, albeit slowly and at huge cost.

This should not come as a surprise. Moscow put its economy on to a war footing some time ago. It appointed an economist as its defence minister and retooled many of its factories to churn out vast quantities of munitions, especially explosive-tipped drones.

While many European nations have dragged their feet over raising defence spending much above the Nato-mandated 2% of GDP, Russias is closer to 7%. Around 40% of Russias national budget is spent on defence.

So Europe has a fair bit of catching up to do if it is to even come close to shoring up its defence and security.

"If the vote passes then it will be significant for Germany and for Europe," says Ed Arnold, senior research fellow for European security at the Royal United Services Institute think tank.

"It will set a precedent and allow others to follow... However, three years on from the invasion of Ukraine the case of Germany is a reminder that more money for defence is necessary but not sufficient.

"Europe needs defence and security leaders who are able to navigate a rapidly deteriorating Euro-Atlantic security environment. Cultural, rather than financial reform, would be most valuable to Europe right now."
