War Will start about soon... I would Say in 7 Days.
So, one week and a few more days to let the armies mobilize and...what a surprise, no war!
No increase in oil prices back to 60$, brent is still at 30$....
What happened, how could your prophecy go wrong?

Is Russia and Saudis affected by this? Sure they are, however they are not idiots neither, while we were buying oil from them and they were getting richer, they invested all of their money into global companies in every nation, if one day all oil ends in Saudi Arabia and they do not make any profits from it, they will still have billions of dollars invested spread around the world.
Invest their money in...wait...what money?
Russia gets money from oil and gas, without that, its economy is almost dead.
Look at the previous oil crisis
- oil goes to 30 from 70, the URSS collapses
- oil drops to 20, the first Russian default happens
They don't have anything but a reserve fund that would not be able to cover the impact from this, remember we're talking about a country which calls itself a global superpower, with huge natural resources and a GDP per capita that matches Romania or Malaysia...
Yes, they are idiots, they sell oil and import refined petroleum products, they even import mining machines and even the equipment for oil exploration.
Behind their entire propaganda, it's one of the most fragile economy in the world.
