The current argument against US Aid to Ukraine is over the current foreign aid package of $5B, which has turned into a culture war issue. I never heard similar arguments in 2016, 2019, or 2021.
Since we are running historic Federal deficits, every dollar we agree to send them comes at the expense of decreasing the purchasing power of Americans.
Government spending at these levels contributes to inflation and makes Americans worse off. Enough is enough.
Ie most of Africa already currently is anti-US (and anti-european) if you didnt notice and welcoming China and russia like long lost brothers, and its progressing.
If US will give us big FU, we will manage russian expansionism on our own, with heavy losses, eventually, despite mostly pathetic leadership (ie germans really know how to put clueless folks sabotaging their own countries into leadership). But we wont ever be friends like we are now.
Magas or similar fringe folks need to put together way more coherent arguments than these, since they dont make any sense from any rational point of view, even if completely US-centric and selfish.
