Geopolitical power is the only reason, especially for the initial decision (USA could have dumped Jews in Palestine & aided them in getting citizenships in the holy land, but that's not how USA gets their marionettes - they instead pump cash intro local terrorist groups until one forms a government & takes over which nets them a sympathetic gov/county reliant on them ... at a human cost we can't even comprehend).

The religious etc reasons are purely what has been used for 80 years by the USA for their purposes (and has since entered, via USAs political power, in the core belief system of their colonies).

Politicians' religion is money and power. Other religions are just a way to manipulate mass opinion.
