Congrats;
After joining BRICS the most important, obviously is develop an alternative payment system to SWIFT, and after it a common currency out of US control.
US cannot fight conventionally Iran anymore without paying an unacceptable cost. So they will continue to the end the economic non-conventional war.
The thing Iran should work on
If economic sanctions would lose in efficiency seeing Iran making products or buying etc, US might go for some other plan involving force
Ex: false flag attack, any kind of excuse to "retaliate" on Iran, nuclear program, they are already trying to get public and even Iranian (diasporas) consent for using force on Iran homeland
Iran should not focus only on being able to target some US assets in the region or being able to reach "Israel", but assets inside their homeland, something which never happened in the history with all the wars of aggression they did, 9/11 doesn't count as an official military retaliation
Major US homeland sites and place Iran NEEDS to have a target on such as DC, White House, private military factories such as P&W, Lockheed, infrastructures inside the United States homeland should be possible to target for Iran, as right now it gives US the psychological advantage that their homeland is 100% protected from any attack, their citizens also have this same view, that they will never face retaliation for any war their regime wages
This doctrine of "one white death equals 100 non-white deaths" needs immediately to stop, western regimes since the of WW2 are traumatized by the idea of having their country struck by a foreign military and having a death count surpassing 10K-20K deaths, this number is equal as if one US carrier completely sinks with all its crew
Psychological targets such as social medias sieges, California region, considered as legitimate targets as they would as always spread terror propaganda on the victim, ministry of information and media sieges as targets
I do not see anything else than US nuclear blackmailing, retaliating inside a country that is currently attacking yours is authorized "when it is proportionate"
