This is both true, and not entirely accurate.
Israel spends something like $24 on their defense. The $3B that the the US gives them (and it's $3B, not $4B, based on what I can find) is largely in the form of military materials: ammunition, bombs, air defense systems, etc. So what we give them is about 20% of their total defense spend, and yeah, that's a lot.
But the flip side of that is that American workers in American factories are the ones building the bombs, missiles defense systems, making the bullets, etc.; the money that the gov't gives Israel ends up creating a benefit for workers in the form of work that wouldn't otherwise exist. I'd have to see a real economic analysis, but this might be a case of each dollar that the gov't spends creating more than a dollar of effect. (And yeah, I know that a lot of that effect is going to e.g. Raytheon shareholders rather than line workers. But still.)
BUT
The fact that we see an economic benefit in terms of jobs and growth by giving Israel aid doesn't mean we should. Because we're directly funding the genocide of the Palestinians.
If the unconscious mind is making the decisions prior to cognition about the thing, how could our will alone affect it? It seems more likely that things outside of our direct control are changing how we are acting, and then the conscious part of ourselves creates the reason that we acted in a specific way.
