It's not surprising that the scientific and technological community is overwhelmingly positive on this issue. Some of Europe's greatest technical successes - in particle physics and in aerospace, for instance - have required multinational collaboration. Such achievements show that Europe can fully match the US if its expertise is coordinated optimally. Bodies like CERN and the European Space Agency, for instance, are underpinned by international treaties: they aren't directly linked to the EU. However the EU has been an important 'facilitator' of collaboration across the whole range of 'wissenschaft'.
