First off, unlike Adolf, Joe Biden is not racist.
Secondly, if you're not American, then you don't have an actual clue what's going on here. I can proselytize about government in Sri Lanka, but since I don't live there I have no idea what it's like. Which means I have no right or privilege to bitch about it.
You clearly don't know anything about American politics.
Yes, our military bombed Syria. No they did not use uranium. Had they done so it would have been Hiroshima 1945 all over again. The region ASKED US TO stop a ruthless dictator from seizing total power and control. Remember that Bashar Assad was using chemical weapons against his own people. Obama tried several times to reach a diplomatic solution, which Assad refused every time. Obama got roughly 99 percent of huge chemical weapons that were stockpiled in Syria removed without us having to fire a shot. In the end, a military strike was the only option left to remove a murderer that was using chemical warfare against the citizens of his own country for his own amusement. Assad had to go. Obama made the call. In turn, Obama saved millions of innocent lives. Thousands died at Assad's hands, and if we hadn't intervened when the region asked millions would have died. Not only in Syria, but other countries. From the fallout, and after Assad attacked his neighbors to try to take over their country.
Obama was a hero in this situation. Not a villain.
