Minor speech copying issue in Ireland

For comparison:

Enda Kenny said in May 2011: "If there's anyone out there who still doubts that Ireland is a place where all things are possible; who still wonders if the dream of our ancestors is alive in our time; who still questions our capacity to restore ourselves, to reinvent ourselves and to prosper, well today is your answer."

Barack Obama in November 2008 said: "If there is anyone out there who still doubts that America is a place where all things are possible; who still wonders if the dream of our founders is alive in our time; who still questions the power of our democracy, tonight is your answer."

If one's audience can recognize "who" spoke/wrote the initial text, attribution is understood to be present, and it's not plagiarism.

Recall Abraham Lincoln's House Divided speech, taken from the Bible.
