With your logic, America should be nuked twice?
I think media thinks that bombings in Syria and other "In war" countries are norm. + I think that France ( And other countries that are helping the country in need of help ) did it for the greater good.
Maybe helping Syria in their Civil war ( Not sure if there even is, not wanting to google facts in this one, pls correct if incorrect ),
so the country and its people don't need to live in fear.
( Sorry if this post doesn't make sense, tried to explain my thoughts as best as i could, English isn't my main language. )
