Seriously? You think this will turn off the US taxpayer Ukrainski spigot? Pipe dream...
The US aid mix is moving even more from financial aid to more exclusively equipment and armaments. The EU has always provided more straight $ aid than the US, and this will increase that contribution.
This is beneficial to the US in several ways. It provides justification for expanding the capacity of its high tech armaments industries, which everyone agrees is undersized for modern requirements.
A similar thing happened in 1915-1917 and 1936-41. Euro arms purchases financed the expansion of US arms industries prior to US entry in WW1 and WW2.
