1. I very much doubt that. The UK has a leverage because it has the power to unilaterally import whatever shit it wants and if Ireland doesn't want to be responsible for meeting EU customs requirements then it's as good as single market access but without many of the downsides of membership for the UK. The EU single market by definition is a very protectionist and developing market when Southern Europe struggles very much and Eastern Europe is in it's infancy so imagine for a moment what the instability of being out competed by far cheaper goods would mean to them ... (we are talking about rising deficits due to capital outflows in places with relatively high interest rates)
3. Article 7 and I don't think it will matter much if the other 26 remaining EU member state won't tolerate Ireland not cracking down on smuggling ... (EU needs to cut Ireland out of the single market and customs union just in case it doesn't install a hard border)
A hard border CAN be avoidable but it means Ireland quitting the EU single market and customs union plus the EU is threatening Ireland if it doesn't take action ... (I guess there are *cracks* within the 'solidarity')
If Ireland DOES want to go the hard border route then they can kiss their chances of reunification goodbye ... (GFA stipulates that Ireland must meet it's end of the bargain in order for Northern Ireland to hold a sovereignty referendum)
Leo and Ireland especially must pick between having their pride (reunification) or it's source of wealth (EU single market) ... (the DUP will make life hell for them)
Aren't you aware how crazy the things you say sound?
You're pro Brexit (no deal Brexit?), a huge part why people voted for Brexit was to regain their "sovereignty" but you want to throw away the new gained "sovereignty" by completly deregulate the UK market. The majority of the working class who voted for Brexit would be hurt the most by that.
And why? In order to damp Ireland in smuggle ware, to either force Ireland out of the single market or to let them break the GFA.
seriously what did the Irish do to you, why are you so angry at them?
