US (specially neocons) ultimate goal is to contain China and Russia. They've been partially successful with Russia since deploying Air defense systems in eastern Europe and now South Korea recently received THAAD system plus Japan will soon join as well ( plus Japan will also be doing patrols in South China sea along with Americans) also Australians have hinted at such joint operations with US navy. Make no mistake the deployment of such air defense systems and sea patrols are to contain China and they're being successful at it.
So while you can laugh about Iran's problems, The Yankees are coming for you right before your eyes ( flinging their ding dong at you by doing patrol in south china sea right in your backyard
) and they will beat you into submission slowly but surely. Also US hostility towards China will never stop and as a matter of fact will only grow stronger as time passes by because you're competing with them to take their place and they don't like it.
Iran is the last bastion of true stable non aligned state and if the Iranians make a deal with Americans somehow( hypothetically and make peace with people of Israel)and solve all their problems once for all, you guys ( China & Russia) will be the major loser of this.
I can see THAAD system being deployed in Northern Iran to further contain Russia's ability to response and as for China they can forget controlling the waterways in their own backyard let alone being able to extract all the resources below the ocean floor plus all major oil suppliers would be in US camp so no more diversification of your oil import and I bet the Russian will stick a high price for their delivery of oil to you. Time will tell who will have the last laugh
