A Malaysian Airlines passenger plane was shot down Thursday in Ukraine, with Americans reportedly among the nearly 300 people aboard, all of whom were killed. Ukraine’s President Petro Poroshenko called the shoot-down “a terrorist attack”, blaming pro-Russia separatists. The rebels have denied responsibility.
Earlier in the day, President Barack Obama offered U.S. help in identifying the cause, saying the crash “looks like it may be a terrible tragedy”, and adding that his administration was working to find out whether Americans were among the dead.
If Americans were killed in an attack, and those responsible are identified, what should be the response of the U.S. government?
