Here is a report from AP, showing Arab displeasure at US arms supplies to Israel as well as Israel's declaration of Jerusalem as its capital.
Guess when this happened?
The report is dated September 12, 1966. Yes, the Arabs were complaining then that the US was not being fair in its policy of maintaining a balance of power between Israel and the Arabs. To them, the US should have allowed them to obliterate Israel.
Even more interesting is their statement on Jerusalem. Israel declared western Jerusalem to be its capital - and even though there are no Muslim or Christian sites of any import in the western part of Jerusalem, the Arabs still said that this was a threat to the holy sites - that they still controlled! (And that they banned all Jews from visiting!)
