Obama did nothing to help these people. He a drew a line in the sand (the infamous Red Line), and afterwards Assad launched a chemical attack against its own citizens and Obama did absolutely nothing. How weak! It's so weak that it's embarrassing.
It’s a no-brainer that Assad is behind the chemical attack. Russia is saying that they think the video is a fake and that chemicals weren't used which gives us great insight into where they fit into the equation and it's clearly not on the side of the rest of the world.
Britain, France, and the United States sent a message to Assad through various bombings of chemical plants and shockingly the United Nations supported it because they want Assad out. One thing about Trump, he certainly isn’t all talk and no action like our previous leader.
