One would think, yes.
Ireland wise, Jews have never been very big in the country. Very small number of them and usually viewed with contempt from both the British and the Irish (even more so by the Irish).
De Valera did have a law passed to protect the Jews in the early 30ies, in views to what was happening to them in Europe, but his foreign minister in Germany was a big simp for Hitler.
Not huge anti-semitism overall, but just a profound indifference to the Holocaust. When Jews were going back home after WW2 or went sent abroad as refugees, Ireland was reluctant to have them back because "that would only exacerbate anti-semitism", only for De Valera to overrule de decision and allow 150 children to be let in.
Then you have the Church in Ireland, adding another layer.
But when it comes to PIRA, and other terroristic revolutionary movements fighting "the oppressor", they came together because they saw Israel as an oppressor. Leading to lots of budying and cozuing with violent "revolutionary groups" and terrorist organizations because they shared a common cause. ETA, FLNC, Red Brigades, etc..
