U.S. Joint Chiefs of Staff Chairman Mark Milley told the Senate Armed Service Committee that “Iran is likely to remain a significant regional threat to the U.S. and our partners and allies. Through its support of terrorist activities and a proxy army inside the borders of its neighbours, along with its ballistic missile programs, Iran seeks to revise the Middle East regional order and balance of power in Iran’s favour”. He went on to assess that “if not constrained through a new diplomatic agreement, their continued nuclear program threatens the emergence of a regional arms race”. “Iran continues to openly threaten to assassinate current and former members of U.S. Government and our military, which is unacceptable”, he added.
