France and the UK have enough nukes to ensure MAD with Russia. It is highly unlikely that the US would stay neutral in a nuclear exchange between the EU and Russia. Country division amongst the superpowers political spheres was acceptable in the early cold war as both sides maintained large conventional armies capable of waging a painful non-nuclear war, and both sides were hesitant to engage in a conflict larger than the one they had just exited (WW2). Accepting that a nuclear power can perform any action they want to except against another nuclear power is a dangerous road. The more likely outcome of which is that neither side makes the launch decision.
