I'd say more likely than not.
Look at our track record when it comes to war and conflict over the past couple of decades. Our leaders clearly have no qualms about destroying the lives of other peoples or those of our soldiers (and their families) when it comes to playing their geopolitical thing. The precedent is clearly there. The recent conscription talk, again clearly shows they have already considered or even made a decision.
These people are dangerously unhinged, they don't live in the reality we live in. Again, German military officials this week got caught talking about plotting to blow up the Crimean bridge - they also revealed Britain has forces already in Ukraine (i.e. SAS, SBS, MI6).
War is the perfect excuse/distraction from domestic issues, and boy does the UK, USA, and EU have that in spades right now. Economically, demographically, culturally. War also gives cover for 'emergency powers', to ram through anything that the pubic might otherwise object to.
We're one phony crisis away from it.
