The USA can't apply sanctions unilaterally.
Wanna bet? All Trump has to say is if you want to do business with Iran, then you won't be doing business with the US.
So the USA is going to apply sanctions to the entire world, doesn't that equate to the USA sanctioning itself?
It's the Trump way. Where have you been? Under a rock?
I thought you were a Trumper?
But you still haven't explained what you think is the reason that Trump pulled out of the Iran deal.
Because Iran were building a bomb or setting themselves up to build one anyway. In Trumps mind, Iran has only becoming increasingly belligerent and sponsoring of terrorism since the agreement so why not sanction them like you would any other state that sponsors terrorism and wants to build weapons of mass destruction. This deal prevented America from applying sanctions Iran deserved (and by Iran I mean their bastard government, not the everyday plebs who inevitably suffer the most from it)
The only thing this deal with Iran gave was a warm fuzzy feeling you were doing the right thing through good intensions. But that warm fuzzy feeling would later turn into someone elses hot, vaporizing feeling when Iran nukes someone they don't like.
