 U.S. Senator calls for bombing positions inside Iran. U.S. Senator Lindsey Graham is urging the Biden administration to blow parts of Iran off the map. He has called for retaliatory attacks and criticized Secretary of Defense Lloyd Austin for not setting clear red lines for such actions. His comments follow increased attacks by Iran-backed militias on U.S. troops in the region. The South Carolina Republican said he told Secretary of Defense Lloyd Austin not to show weakness and make clear what the U.S. red lines for a retaliatory attack are. Without Iran, there are no Houthis. Graham told Fox News. The Houthis are completely backed by Iran. I have been saying for six months now, hit Iran. They have oil fields out in the open. They have the Revolutionary Guard headquarters you can see from space. Blow it off the map. He continued, If you really want to protect American soldiers, make it real to the Ayatollah that if you attack a soldier through a proxy, we're coming after you. Graham's comments follow attacks by Iran-backed militias on U.S. troops in the region, which have stepped up. There have been more than 100 attacks on troops in Iraq and Syria this year. The controversial statement has raised concerns about potential nuclear proliferation and added to geopolitical tensions. Iran's substantial active military strength of 610,000 soldiers further heightens the situation. Senator Graham's comment is likely to face criticism from those advocating for diplomatic solutions and could potentially escalate the rhetoric surrounding the U.S.-Iran relationship.
