We don't give anything! We sell weapons.
This was US President Donald Trump's response to the question of how he plans to provide military support to Ukraine in the future. The visit to Washington by EU leaders and Ukrainian President Volodymyr Zelensky sealed the previously established system that Europe will now pay for American weapons supplied to Ukraine.
The Washington administration has already indicated that the warehouses there are also emptying, but there is a more compelling argument for Washington to put a price tag on the weapons: Why give them away for free when you can do it for money? The decision was a direct result of Donald Trump's policy so far, which has prioritized the promise of a good-sounding deal over everything else. Which the Europeans will apparently take advantage of, since there is a surplus of many of the types of equipment required by Ukraine.

There has been a lot of brainstorming about who would buy what from the US, and for how much, but an article published recently by the Financial Times, which has access to the draft documents, reports that the new cycle will be institutionalized in a contract. According to it, Ukraine will acquire US weapons worth $100 billion, financed by Europe in exchange for “accepting security guarantees from the US after a peace treaty with Russia.”
In addition, according to the draft, seen by the Financial Times, Kiev and Washington would sign a $50 billion deal to manufacture drones with Ukrainian companies that play a pioneering role in developing the technology and using it against Russia.
