Is Russia really that dangerous?
More than that - right now it's on par with ISIL (though - in different ways) - one of 2 biggest threats to Western world
Um, no.
Only in the sense that it is a much bigger threat than ISIL.
Almost every state in the world is a bigger existential threat than ISIS. ISIS are bunch of goat-inking slave keeping vermins, who have succeed in filling a power vacuum, but who will be exterminated the first time Turkey, Saudi Arabia and Iran decides to use five minute on finding a power sharing compromise or the minute USA decides to send in land troops.
So you're saying that ISIL is going to around for quite a while. As you pointed out ISIL isn't a threat to the US, so we're not going to send in ground troops beyond maybe some special forces in Iraq. The idea that Iran and the Saudis would agree on anything is also laughable. I wouldn't be surprised now if the Syrian Civil War didn't last another decade so as to be at least as long as Lebanon's was.
