President Trump has dismantled Iran’s military capabilities, destroyed nearly 100 percent of its military factories, and buried its nuclear program. We are now entering the endgame. At dawn begins an economic D-Day — the single greatest financial offensive ever marshaled against an adversary. The Islamic Republic has subsisted by dressing extortion as security guarantees. It has drawn strength from a calculus that regards Iranian retaliation as certain and American enforcement as negotiable. Under President Trump, that era is over. And those who fear the danger of defying Tehran ought not to discount the cost of testing Washington. The President has created the conditions to leverage every agency, every authority and action many assumed we would never summon. Our objective is to sever every economic lifeline that sustains the tyrannical regime until Tehran stands alone.
