Obama was asked why Iran didn't have to give up their terrorists activities, their hegemony or even recognized Israel's right to exist as part of the nuclear deal. He responded that it was unfair to ask Iran to do this since it would require the regime to change radically (paraphrasing). So Iran gets the sanctions lifted if they promise to wait 10 years before they can produce a nuclear weapon (Obama recently said their breakout period would be zero months at the end of this agreement).
Reagan, on the other hand, came into office with an adversary as thuggish as Iran, only much bigger and more powerful. Reagan could have decided that the Soviet Union couldn't possibly change and that he would simply negotiate whatever deal they would agree to. But that wasn't Reagan's belief. He used every means possible to suffocate the Soviet Union, economic, diplomatic, military and weapons development including SDI. We all know that the Soviet Union did eventually collapse winning the Cold War for the U.S.
Leadership makes a difference.
