For sure they don't want to give it up for free ! Just like any country Iran want to defend its interests, to play its hand the best it can... And leverage in many countries (now even in Africa) and the nuclear weapon are "trump card" in the game, so they reinforce it for now... They will wait for the next US election and see how they can work something after it
"Iran want to defend it's interests" : well arguably bringing your country to the brink of economic collapse due to American sanctions isn't in Iran's best interests. We will see what the new American president (could be still Trump btw) is gonna do.
There is NO WAY any Iranian government would simply give up its rocket program, specially when literally every power around you has them. Specially when they don't have an Airforce.
Iran has complied and tried to work with the international system on the nuclear question. They have behaved pretty reasonably going back to early 2000s. Their demands and programs are not outrages if any other country had made them.
The US wants to destory and overthrow all of their allies and the have bases in basically every country around Iran.
In reality econoimc sanctions do not collapse a country, the evidence of that is pretty clear. And it doesn't lead to regimn change either.
