US Secretary of Defense Pete Hegseth said that the cost of war with Iran has reached about $55.5 trillion so far. This amount includes military salaries, operating and maintenance costs, etc. Secretary Hegseth avoided answering questions about the possibility of destroying Iran's underground nuclear facilities, but acknowledged that China and Russia are supporting Iran. He said he had a way to suppress this cooperation. In addition, Secretary Hegseth pointed out that North Korea concealed its nuclear capabilities by strengthening its conventional forces, and analyzed that Iran is also pursuing nuclear development through the strengthening of its conventional forces.
