The United States in another Middle-East civil war

For months, State Department officials and a few members of Congress have warned that America's at risk of violating international law. Until today, it was all about US military aid to Saudi Arabia's bombing of civilian targets in Yemen, its tiny neighbor already devastated by civil war. Today, an American warship fired cruise missiles into Yemen — in retaliation for shots fired from shore -- making the US more directly involved than ever.  Now Iran is sending ships to the region -- escalating an already tense international situation while a humanitarian disaster unfolds on the ground.
