Not eve close. The US supports Israel because it is the only true democracy in the Middle East.
You typed the truth. Israel is surrounded by hostile Muslim Sharia law countries. If it wasn't for the US they would have been destroyed. No one cared about that little section of middle east until the Jews turned into the jewel of the Middle east. No, so called Palestinians didn't rule there. No one can even show a Palestinian coin prior to the Jews taking that little barren section of land. What you can find there is archaeology proof of Jews being in the area for hundreds and thousands of years.
Getting back to the US's greatest ally it has to be China. China is building the most powerful military on earth with American money raised from buying their crap. Every year the US hands China $452,576,771,000.
