Obama ever agreeing to that deal or to the Paris Agreement were acts of vandalism against American national interests. There is a reason he never submitted either to the Senate for ratification.
Trump just set things right.....ie he obliterated what Obama did.
Trump did far more than that.
Trump effectively cut off Iran at the knees. He caused serious loss of oil sales. He seriously disrupted their economy there by disrupting there surrogate funding. He recently had a brit capture of an Iranian tanker delivering to Syria.
Trump effctivly fight back with mines on tankers. Iran shot down aa drone a near act of war. They are at their wit’s end. They have no place to go
