Russia in the Middle East…still?

Why do other countries allow Russia to be apart of the Israel/Palestine peace process? Isn’t having the UN, US and EU involved enough? Does Russia matter or do they offer any valuable insight to the matter?

ANSWER PERSON RESPONDS: Russia does have a history with these countries, relationships which, though they may based on Cold War confrontations, still carry some weight in the region. And in case you haven’t noticed, the UN, US and EU have not been able to solve this one. Adding Russia to the mix may not help, but we need to be open to anything. It is too important.
