China is a super-power and is holding USA by the balls. China has 2-3 trillion dollar reserves of USA treasury bonds. If China releases them, USA dollar will crash.
Russia is controlling EU by oil supply. Russia is a major technological power in defence and has China to supply its goods. USA can do nothing to Russia.
Turkey has nothing to offer anyone. It has deficit of about $50 billion and no major infrastructure for manufacturing or high technology goods. Turkey is highly reliant on foreign money from Qatar and other places for keeping its economy in place.
Iran and Pakistan alliance will make Saudis very angry. Don't forget that Saudi and Pakistan have military alliance and an alliance with Iran will seriously worry Saudi that they are losing influence
This is a very funny scenario you are speaking of.
