Does Obama know how Ireland voted on the Lisbon Treaty?

I'm being facetious. I only finished reading his Berlin speech and came across this:

This is the moment when every nation in Europe must have the chance to choose its own tomorrow free from the shadows of yesterday. In this century, we need a strong European Union that deepens the security and prosperity of this continent, while extending a hand abroad.

Doesn't he know that Ireland has put paid to the notion of a strong European Union, particularly one committed to European security?
