Need to look at military aid specifically
You need to read my original post again.
Most of the funding already comes from Europe. A change of course in the US would increase funding from Europe even more.
There are factory lines being built all across Europe, the domestic EU production capacity of artillery shells has already tripled since 2022 and is bound to increase further.
EU invests both public and private funds into Ukrainian domestic facilities, which are also increasing their production capacities. Without non-military funding, this 2nd order effect would not be possible.
So your brushing off of non-military funding makes no sense whatsoever. It enables Ukraine to achieve its military goals. They now produce most of their drones domestically, they source most of their arty shells outside of the US, etc.
To say that a change of course in the US will bring peace in Ukraine is to say you have 2 braincells and are a Trump supporter with zero idea about the war in Ukraine and no military expertise to speak of.
