Not really. The Soviets were attempting at that time to gain influence in the Mideast. The US was trying to block them and eventually replace Britian and France who were both hated amoung Arab nationalists as colonial powers as the lead influence in the mideast. And it was all about oil.
Also don't forget that the Soviets threatened to nuke London, Paris and Isreal during the crisis which would have set off WW III. Probably an idle threat, but no one knew for sure at that time. Keep in mind, the Suez Crisis was going on against the backdrop of the Soviet invasion of Hungary.
It really had nothing to do with Commies in the State Dept. Eisenhower himself called all the shots.
The Israelis had a lot to hide at the time, including the fact that they initiated the [1967] war.
Israel freely admits firing the first shots. But they knew damn well from their Intel operations that Eqypt, Syria, Jordan and Iraq were ready to attack them in a matter of hours or days. We knew it too. It was a gun fight and Israel was quicker on the draw. The attack on the Liberty happened several days after the war began. Any intel they may have had on initiating hostilities would have already been reported.
Okay, but it is still more believable than the IAF mistaking the USS Liberty for the El Quseir.
