Nevertheless, the practical effect of the statute is somewhat limited because it recognizes the power of the president to unilaterally deploy military forces when necessary.

The president's legislative power is limited to approving or disapproving bills passed by Congress. If the president approves a measure, it becomes law. If he vetoes the bill, or refuses to approve it, it goes...
