ELI5: Obama's nuclear policy. What is it, why are Republicans so against it (besides simply partisanship), and what impact does it have on me, the average person?

The initial interim agreement involved the West decreasing economic sanctions in exchange for Iran suspending its nuclear program.  However, there was a fair amount of suspicion that Iran wasn't actually sacrificing anything because it needed to rebuild the infrastructure needed to continue.  Couple that with the lack of verifiability and it appeared to many that Obama was trading away real concessions for nothing.

The current deal appears to be even more lessening of sanctions without any significant hindrances to Iran's development of nuclear weapons.  Effectively, Obama's critics are arguing that he has accepted Iranian nuclear weapons as fait accompli and wants to normalize relations in attempt to give himself a 'legacy' while possibly gaining cooperation on ISIS.
