Monday's agreement on a draft deal to form a tripartite coalition government in Dublin after two months of hard bargaining is to be welcomed, not just in the south but also in the north in this vital post-Brexit period.
The leaders of Fine Gael, Fianna Fail and the Greens emerged from their negotiations with broad smiles and a palpable sense of relief that a deal has in fact been done.
However, as the old saying goes, there is many's a slip 'twixt cup and lip, especially as the three parties involved have to sell the deal to their respective members.
This will involve the paper balloting of members throughout the country, as no conferences can take place during the Covid-19 crisis. It is very likely despite some internal resistance that both the Civil War parties, Fianna Fail and Fine Gael, will endorse the coalition deal.
The big worry for Fianna Fail is that they are trailing badly behind Sinn Fein in recent opinion polls and they must be very anxious to seal a deal that will guarantee them returning to high political office after nine years in the wilderness.
Fine Gael on the other hand can actually afford to ride out the rejection of any proposed deal because of the surge in popularity of Leo Varadkar in the opinion polls, due to his successful leadership through the worst of the Covid-19 pandemic.
If this deal fails - and that is not impossible - the likelihood would be a general election in the autumn and the emergence of a rejuvenated and stronger Fine Gael, who could dictate the shape and form of any future government.
An autumn poll would also give Sinn Fein a chance to maximise their support and do further damage to Fianna Fail.
Therefore, the worst outcome for Fianna Fail would be a failed deal.
Being outside of the negotiation loop may well suit Sinn Fein, as they probably regard going into government at this challenging time to be a poisoned chalice.
As a populist party they do not want to make difficult and unpopular decisions the new coalition will surely have to make.
It also suits them to appear to be excluded. They are past masters at playing the victim.
But given the volatile atmosphere within the ranks of the Greens there is no certainty that any draft deal will win the necessary two-thirds approval from their new and more militant members. This includes members in the north. The Greens are split between the traditional longer serving members and the newer, radical intake that formed the backbone for the party's vibrant election campaign.
The Greens have impressively attracted up to 3,000 new members over the past couple of years. They are in the main idealistic eco-warriors, who are intent on achieving radical social and economic change that will bring about a new Green agenda in the south.
Their leader Eamon Ryan is an intensely likeable TD, who sees the need to turn the Greens from being simply a party of ecological protest into a party of government in order to bring about attainable environmental change throughout the country.
However, Ryan's pragmatism is hotly contested by a radical membership, intoxicated by their success in the last election, where they did the impossible and dramatically won 12 seats.
But their environmental idealism has clouded their thinking. Despite his outstanding electoral achievement, one of Ryan's TDs is even challenging him for the party leadership next month.
They could learn much from studying the Greens in other European countries and their tactical participation in government.
The message for the Irish Greens is that you need to be in power in order to advance the Green revolution.
At last after nearly five months of a caretaker government and parallel coalition negotiations, the details of a joint three-party agreement is emerging.
If Covid-19 hadn't dominated everything since the general election, then the current paralysis of the Dail would have been exposed to public ridicule.
If the various media sources are right, it is the Greens that are the real winners of these negotiations by having successfully negotiated a seminal policy deal on climate change measures, and in particular the commitment to a 7% average annual reduction in carbon emissions up to 2030.
That in itself is a major achievement by the Greens, in bringing the established parties to embrace such a radical programme to counteract the impact of climate change in Ireland. This huge win will be transformative.
But while the Greens are winners, we should not overlook the core achievement of this agreement, which is the coalition between Fianna Fail and Fine Gael and the end of Civil War politics in the south. Now that really is a prize well worth celebrating.
