And I think what's happening in Gaza is unconscionable."[69] Calling for aceasefire in theGaza war, Harris said: "40,000 dead in Gaza is a milestone the world must be ashamed of. International diplomacy has failed to protect innocent children, some only days old."[70] Ireland announced therecognition of aPalestinian state on 28 May 2024, a move he described as "important and historic".[71]
In April 2024, Harris said that Ireland would not provide a "loophole" for other countries' immigration issues.
