Lessons for Israel from the Ukraine.
It is interesting to remember that, with the break-up of the Soviet Union, much of Russia's nuclear missile facilities were located within the Ukraine.
In return for the Ukraine disarming it's nuclear weapons, America and Britain guaranteed its national integrity and security.
It is clear that the US and UK will not send troops to counter any Russian invasion of the Ukraine.
Israel is watching this and questioning the value of any international guarantees linked to its security considerations in any peace deal with the Palestinian Arabs.
Israel is also dubious about the effectiveness of any American guarantee to Israel in their dealings with Iran over Iran's nuclear ambitions.
