Leo Varadkar dishes out the tough love, actually

Has Leo Varadkar miscalculated, however slightly, and missed a golden opportunity to subtly stack the Brexit deck? 

Or has his tough-line stance in recent days allowed him to do just that, as he strategically opens up space for fresh alternatives to resolve the Brexit stand-off now he has Britain’s attention?

The questions, while not receiving much air time to date, should be considered after Varadkar’s frosty welcome from the DUP in Belfast yesterday.
