UGG. Stop with this false "the US is just as bad" bullshit. It is 100% intellectually dishonest. It is Alex Jones level bullshit.
The west is constantly asked to intervene. You seem to have an incredibly short memory. You might want to read up on Rwanda to see what happens when the west does absolutely nothing.
Was the US asked by the afghan government to intervene in the 1980s? No, they asked the russians, which then intervened. What did the US do? Invite the radical islamist Taliban to the white house and arm them heavily. Country is still fucked today.
Was the US asked to invade Iraq in 2003 and destablize the entire region for decades, create a power vacuum that would eventually lead to the foundation of ISIS? I don't remember so.
Was the US asked to intervene in Syria by any authority? No. Russia is there because they were begged by Assad, the head of state, to intervene. They are legitimized, even if it's a despicable thing to support a dictator with so much blood on his hands like that. The US is still arming and supporting rebels in the meantime. And AGAIN, go look up those rebels. Those are not some noble freedom fighters, those are mostly radical islamists that cut off their enemies heads and pose with them, fight along Al-Nusra etc.
Same with Lybia pre-Gaddafi. The West bombed shit and delivered guns to (eventually radical) rebels and then wonders about all the refugees and instability.
Which is why imo it's ridiculous to say somehow having Assad in power is the problem. How can anyone seriously believe that removing Assad would do any good in the current situation? Those radical islamist terrorists aren't suddenly going to drop their weapons because someone installs a new puppet leader.
You might also like to look up how many civilians/hospitals US-led forces bombed so far in 2016, in case you missed that in the news. So again. There is NO good force in this war. Not russia, not the US, not the arab countries, not Turkey. Having an extremely narrow, pro-american view of things really isn't helpful when trying to stay at least semi-objective.
