Iran was funding terrorism, they took American hostages, they put a "hit" contract out on the POTUS and tried at least once to assassinate him, ....
(and the one you continue to overlook) ....they lied at the start of JCPOA and were hiding parts of their nuclear development program JUST AS WE TOLD YOU THAT THEY WOULD.
You think Iran decided they couldn't trust us when instead, they just understood that the new leadership wasn't as gullible.
We told you Iran would cheat and they did.
We told you that we would end this one sided appeasement program without congressional support, so don't do it. But you did it anyways.
Peace through strength (strength comes first). This is not a pithy bromide. it is a truth when dealing with terrorists.
Iran has been offered multiple chances to avoid conflict if they would simply stop funding terrorism and stop seeking nuclear weapons. They wouldn't do it.
These were the people that you were offering appeasement while at the same time showing erratic and, at best, lukewarm support to Israel under BidenHandlers.
Your party is full of "From the river to the see" people, they fly Palestinian flags, they support Hamas, and you are feeling sympathy now for Iran that they "couldn't trust us".
Iran would use their nukes against us and they would black mail Israel and us the moment that they had the ability. They have said so. That is the only promise that can be believed from them.
