> Doesn't Israel buy most of those solutions from the US?

No, the Iron Dome was developed by Israel. US funding only came at the end of development, during production.

> Also, the rockets coming out of Palestine are a lot different than what would be lobbed at the US.

People always forget about: https://en.wikipedia.org/wiki/David%27s_Sling and https://en.wikipedia.org/wiki/Arrow_(Israeli_missile)

Both of those linked projects had large US defense companies involved (Raytheon and Boeing) in development and manufacturing.

I believe the Iron Dome was funded by the US, i agree the situation is different. The US is also positioned very far away from any country that would lob rockets at us.

Production was funded by the US, but Development was not, it was entirely in-house.
