They talk about him like he’s a king, but he’s not. He was elected, twice. Now of course, we don’t know much about the nature of these elections, and whether they were like the “elections” of Saddam Hussein or not. But in the long run... unless they take out ISIS too, we’re just making things worse.
If Assad and Russia were really fighting ISIS, that would make sense.
This is what I think Trump discovered. Trump was under the impression during the campaign that he could form an alliance with Putin and possibly Assad to fight ISIS.
Once elected, Trump discovered what a lot of others have been saying, that Russia is there mainly to maintain their warm water port and keep a friendly regime in power. They are not fighting ISIS too much.
Is it our concern? Maybe not.
