Germany announced they will halve the support

No. While that is a popular narrative in media living of enragement bait and doom scrolling, Germany has announced nothing the like.

That is with a higher budget for their military from which a lot of Ukraine support came directly and with Ukraine now getting 50 billion covered by the interests of Russian money frozen.
