No. they mean, no matter who you vote, the us won't do jackshit

Edit: punctuation for better readability

Like saltyiceteamaker said, US won't do jackshit about what Netanyahu doing regardless on who you vote, and even if they don't give them money, highly unlikely Netanyahu will just stop doing what he's doing.

However, for other issue within US or the one affect the world, it have different impact between this two. US is one of the biggest CO2 emission country, and also the world exporter of methane, for example.

Are you aware that the only way Israel is waging their war with guns and bombs is because of the US selling them the weapons? I'm sure Israel would still want to commit genocide without them but would find it much harder to do with literal sticks and stones.

Probably not until it's citizens are able to vote outside the two party system in a reliable manner.
