If there is no deal before brexit then Ireland has a major import export problem. As yet they have done zilch to alleviate this problem, in fact they are trying hard to stir things up. Do they want to restart the troubles? It certainly seems like it from my perspective. The only scheduled ro ro services to europe are to roscoff and santander. Neither location is suited for northern european trade, where the bulk of the action is. The EU either stops squabbling about a UK transit for Irish traffic or Ireland has to magic up some alternative regular scheduled routes to Europe. This needs to be done without impacting existing scheduled services. As I have said repeatedly it is an Irish problem, they need to negotiate a solution. They can threaten brexit all they like but how do they seriously think they can prevent it. They appear to have a negotiating position derived from swimming in Guiness for the last few months.
