Depending on how things work out, the GCC countries could end up deciding that China is a better partner than the US, due to their higher level of influence in Iran and with Iran’s biggest ally, Russia. That would hasten the end of the petrodollar and advance Xi’s multi-polar world. I wouldn’t be the slightest bit surprised if Xi is pulling Iran’s strings to achieve that outcome. It would be a huge geopolitical shift and a big win for China, Russia and Iran. I see Russia is already moving back into Tartus in Syria, maybe a sign of things to come.
Fortress America time.
If we did nothing and let Iran bring their nuclear ambitions to fruition, how would that lead to stability for the region and for us? How would WWII have ended up had Germany obtained a nuke before we did? Is there any way, outside of the end of the IRGC and the radical Islamic theocracy, that Iran would partner with anyone else but our enemies?
Why would the GCC countries want Iran to get nuclear weapons and for their current regime to stand? They would become pawns to Iran, China, and Russia.
Also, remember, it was our more 'thoughtful, rational, gentlemanly, and reasoned' Republicans, like HW Bush, who started the ball rolling for advancement of China's economic gains and power in the world.
