You mean like threatening to declare a no-fly zone over someone else's sovereign territory and then threatening to shoot down Putin's aircraft operating there at the invitation of the head of state of that sovereign territory for the purpose of defeating our soi-dissant common enemy ISIS. - that kind of dangerous and incoherent.
Oh and did I mention that you are doing this because the guys you are supporting to attack ISIS are really making common cause with ISIS, but you have this policy on the grounds that well they maybe SOBs, but they are your SOBs, so you think, and Putin is targeting them because they are getting in the way of attacking the so-called common sworn enemy.
