Telegram/Communique Archives (Specifically Soviet, Israel, US)

Hi.

I've just signed up here so hello to everyone

Atm, I'm doing some research for a school assignment and I would like to find some telegrams/communique archives for the following countries.

-Soviet Union
-US
-Israel
-Egypt
-Syria

I have tried googling but I am not quite sure where to look, and I figured that this might be a good place to ask.

Thanks so much,
