US fears escalation of war, prospect of Iran becoming 'directly engaged'

The United States is concerned about the possibility of an escalation in the war between Israel and Hamas, as well as the potential involvement of Iran. The White House National Security Advisor, Jake Sullivan, mentioned the risk of a new battlefront on the Israel-Lebanon border and the potential direct engagement of Iran. The US has taken measures to prepare for any contingency, including deploying aircraft carriers to the region. Iran has long supported Hamas and Hezbollah, providing them with funding and weapons.
