Russia wouldn’t do this....unless it was paid as a service...likely from the Saudis. In recent months, the Saudis have come to realize the bigger issue is ISIS and they need to be put down. The only military thug-Army left....is Russia. It would be curious to know the actual number involved.
I never thought of that....instead of payment could the Saudis have agreed to raise the price of crude - I am hearing hints that the Saudis will constrict the flow of oil to boost prices now...
