No, @MariaLuna is correct that there's no real equivalence between the Northern Ireland and Israeli-Palestinian conflicts.
Bar the clear fact PIRA was part an international terrorist network with Hamas, Hezbollah, ETA, ANC'S MK, FARC-EP, Colonel Gaddafi's Libya and Iran. PIRA regarding the two conflicts as "one struggle" really doesn't make it so! 🤷♂️
What you're is missing is that PIRA and UVF didn't control vast swathes of Northern Ireland.
Hamas controls Gaza.
Because of that reality most Catholics and Protestants didn't support these terrorist groups.
On the other hand, because Hamas controls Gaza most Palestinians support them.
Immediately, your comparison with Northern Ireland is defeated.
And I speak as a Northern Ireland Catholic too whose family always opposed PIRA.
It is the ignorant or PIRA supporter who would seriously link the two. And provide an oversimplified, distorted history to "prove" it as well. History really doesn't work like that!
You might as well say that European countries are similar to Israeli-Palestinian conflict since similar things happened.🤦♂️
