@AmbJohnBolton Jan 3 More Congratulations to all involved in eliminating Qassem Soleimani. Long in the making, this was a decisive blow against Iran's malign Quds Force activities worldwide. Hope this is the first step to regime change in Tehran.
John Bolton Verified account @AmbJohnBolton 21h21 hours ago More Another good day. Iran rips the mask off the idea it ever fully complied with the nuclear deal, or that it made a strategic decision to forswear nuclear weapons. Now, it's on to the real job: effectively preventing the ayatollahs from getting such a capability.
I think John Bolton is fully in President Trump court. He has nothing to gain or moral position for turning on the President. Unlike Senator McCain, He will not let opinion differences get in the way.
