Senator Lindsey Graham (R-SC) wrote on Twitter, Monday, "Just received a briefing from National Security Advisor Bolton about escalating tensions with Iran. It is clear that over the last several weeks Iran has attacked pipelines and ships of other nations and created threat streams against American interests in Iraq."
Graham concluded, "The fault lies with the Iranians, not the United States or any other nation. If the Iranian threats against American personnel and interests are activated we must deliver an overwhelming military response."
