Or you could read the article and see that’s not even remotely the issue, and the title is as per usual misleading.
Germany planned 8 billion eur financial support for Ukraine this year. That’s been used up. So, no more monetary (!) aid unless they find some spare change in the budget, which they won’t.
And to preempt the next headline: Germany’s spending next year on Ukraine will be halved, yes… Because there’re plans for an international fund.
Also while “Olaf” is the one naying further spending, he’s not doing so independently of the ruling coalition. He has little agency.
