Well, mostly.
Krugman shared this chart, as part of an argument that it’s ridiculous for Europe to be scared of Russia:

GDP indicates the value of the parts of the economy which are subject to money. (If you do something but don’t use money, it doesn’t get measured.) As such it theoretically measures how much you can mobilize using money. Back when most people lived off commons, before that was enclosed, and didn’t need to do much paid labor, you couldn’t mobilize much.
But that’s theoretical ability. It’s important, but what matters is what you do with it.
And the thing is that Russia does with it is build drones, advanced missiles, advanced jets and other weapon systems. And they build them in large amounts. Europe’s production of weapons is much smaller, and they’re less advanced than the Russian weapons. Russia also produces lots of oil and natural gas and has a huge refinery sector. They have a lot of rare minerals and resources in general. And they do still have both heavy and light industrial sectors.
Meanwhile Europe is hemorrhaging industrial jobs and its industrial energy costs are much higher than Russia’s.
So Europe may have more theoretical economic capacity, but it can’t translate that capacity into state capability where it matters. Russia is stronger than Europe.
It’s not that it necessarily has to be this way, but for Europe to match Russia it has to maintain and expand its industry, find cheap energy, and source natural resources that are scarce in Europe. It also needs a lower cost structure than it has in general terms.
These are not trivial problems. Europe is pushing on renewables, to be sure, but has some way to go and effectively has to buy those from China. It needs to get resources like oil and minerals from other countries and the closest and cheapest source of hydrocarbons, which it needs during the transition, is far more expensive than it otherwise would be. American oil and natural gas is FAR more expensive.
The other traditional source of resources was Africa: mostly ex-French colonial possessions. France never forgave their debts, had military bases all over and often forced them to sell resources at very low prices. But now that Africa doesn’t need European goods, they’re kicked the French out and raising prices and moving to do primary processing domestically.
So sources of cheap minerals are drying up.
All of this could be worked around, if Europe was a technological leader, but…

Now legacy industry matters. Machine tools. Steel. Chemicals. Stuff that Germany is good at. (Automobiles are dying, because yes, the future is EVs.) But Germany and Europe are losing those industries. And they aren’t producing the industries of the future. Everything they have is basically legacy industry, developed in the late 19th and 20th centuries. They aren’t creating, mostly, the industries of the 21st century.
GDP only matters if you can use the resources it suggests you have to produce what you need. When it comes to competing with Russia, Europe’s ability to do so is limited. Not non-existent, Germany has significantly increased artillery shell production, for instance, but not what it needs to be.
Without a colonial empire and without resource rich nations willing to trade Europe the resources it needs at reasonable prices, and without a tech lead, What does Europe have?
Very little.
And this is why Europe’s in for a long fall. There’s no easy route out and no one is even talking about doing what’s right. The center still thinks that the problem is that workers have pension and time off, the rising right are complete idiots who think the US is a good model and the left is not, in most cases, in contention. Germany’s AfD will not make Germany better off, it will continue destroying Germany. The same is true of UK’s Reform part and France’s right wing.
GDP is a stupid stat. It conceals more than it reveals. It doesn’t tell you much about the structure of a country. India, which in GDP terms is a great power just lost a minor war to Pakistan. High GDP can actually be bad, since it includes waste, billionaire income that does nothing for the country, and all the money earned in harmful industries like finance and private equity.
Europe’s high GDP isn’t meaningless, precisely, but it isn’t what matters. If it was, Ukraine would have won the war already and the EU wouldn’t constantly be on its knees groveling to America.
What matters is what an economy CAN do. And Europe’s economy can’t create what Europe needs.
