The war in Syria has been going on for over 7 years at a cost of hundred thousand of lives and total disruption of the population. Little has been done by the world up to now,and we have come to know that the UN is completely useless when it comes to conflicts like this. Obama's line in the sand meant nothing, and the recent gas attacks confirmed this. For those that would criticize Trump and the U.S. for their actions, what was the viable alternative, as after 7 years diplomacy was not and never was going to work. We could have course turned the page and said not our problem, but we have done that too many times in the past and we are supposed to be better then that.It was clear years ago as it is now,  Assad will have to go, either willingly or by other means. Trump has sent a message that has been heard very clearly by those in the Middle East , Russia, China, and North Korea, and the message has been understood.
