The US had hundreds of thousands of troops on the ground in Iraq for over a decade. More than half a million Iraqis died. There was intense violence between different religious groups and political factions. But you come here and say that everything would have magically gotten better with more US involvement in Syria. A direct American intervention in Syria probably would have made things even worse. Droning Assad, a…
Notice how I specifically talked about Syria and Libya. I (along with a lot of other people) opposed Iraq war as well and it took you to pull it here for lack of consistent argument. Don't see the point arguing with you further. Some day both Putin and Assad are going to be dead and I hope they suffer in their last minutes. I will be cheering while you will be mourning your tyrants.
Just imagine the chaos in Syria if the Sunni extremist groups that the US supported had won. How would the various religious minorities, like the Shiites, Alawites and Christians, have fared? What's the chance that the Sunni extremists would have carried out genocide against religious minorities? It's one thing to say that Assad is a tyrant, but another to say that everything would be better if the US toppled him.
In Iraq, supporters of a US invasion made the exact same argument. "Saddam is a tyrant? Why don't you want to get rid of him?" The US toppled him, and half a million people died as a result.
Your analysis - everything will be better if the US topples tyrants (and realistically, empowers people who might be even worse) - is very simplistic, and has a terrible track record in the real world.
