Russian aggression and US isolationism push a once hesitant Germany to invest heavily in defence.
Germany's military, the Bundeswehr, recently got the all-clear for a massive increase in investment after parliament voted to exempt defence spending from strict rules on debt.
The country's top general has told the BBC the cash boost is urgently needed because he believes Russian aggression won't stop at Ukraine.
"We are threatened by Russia. We are threatened by Putin. We have to do whatever is needed to deter that," Gen Carsten Breuer says. He warns that Nato should be braced for a possible attack in as little as four years.
"It's not about how much time I need, it's much more about how much time Putin gives us to be prepared," the defence chief says bluntly. "And the sooner we are prepared the better."
It feels a bit weird being on the German side for once, also their track record of succeeding isn't that great, but I love our neighbors and I fully support them.
I'm just, sad the world is falling into another world war while we also just could be more kind and forgiving towards each other. It would save a lot of lives and leads of pain and agony.
I feel like this is a good idea but I also saw what Germany did to Brazil in that World Cup and there needs to be a plan for them going too far and hurting people just for living.
Great powers rearming will not be good for anyone no matter what the context is around it. After Napoleon, European leaders were so afraid of war between great powers that they avoided it for 100 years. The moment they let their guard up we got WW1. The weapons do not make us safer. Don't think for a moment it can't happen again.
