Desmond is a difficult nation to play as, because as soon as England has recovered 60% of its manpower, it will gain claims on all of Ireland. This will usually happen after the initial Surrender of Maine and war with France and after the war of the roses.
Initially there are two different choices. Try to stay in Ireland or try to flee to the new world. If you plan on staying in Ireland, prioritize annexing as many Irish provinces as possible and choose military ideas. If you plan to flee to the new world, take colonization ideas, discover America, and colonize less than five provinces in a colonial region. This is very important, as otherwise, it will form a Colonial Nation.
