You both have valid points that are most likely both true.

Reality is more complicated thatn theories. Israel is a US vassal and completly depending on the US. The US needs Israel to assert power in the region. Israeli actors are influencing US politics. US actors have personal interests in Israel. US actors are depending on pro-zionist fundamentalist christian groups. Israeli actors are controlling parts of the US entertainment and news production. Other local players in the region depend on the US and thus support Israel to secure their own power. Racism in the general public is also part of this (some headlines produce more click, than others). And so on and on.

Imo these are all correct assumptions, but even this doesn't show the whole picture. Reality is too intervowen to completly access it in simple terms.
