Trump's nuclear saber-rattling could suggest he feels emboldened after ordering the bomb attacks against Iranian nuclear sites.

Former Russian President Dmitry Medvedev followed up this claim by writing that Russia had "no intention of supplying nuclear weapons to Iran."

Trump's decision came after Israel and Iran have exchanged consistent strikes since June 13. Israel had urged the U.S. to target Iran's nuclear facilities, saying that Tehran was moving close to creating a nuclear weapon. Iran maintains that its nuclear program is for civilian, not military, purposes.
