Korea, Vietnam and Iraq - only to name a few of the majors - are now a threat to interfere in Syria's affairs.
The first three invasions did not really achieve much, and to take military action in Syria might really stir up a hornet's nest.
I, for one, wish that the United States of America would pay greater attention to addressing its own internal affairs.
Don't misunderstand me, I utterly abhor any attack involving the use of chemical weapons. But for another country which is not really involved with this to start with to jump in and crack the whip in this way is definitely not the path to take.
The USA does not have the automatic right to take military retribution within and against other countries.
