@Walter Hinteler,
I agree that NATO is not what it once was - members were formerly more united, and by a then real, and proximate common enemy. That is no longer the case. Since then the U.S. has badly overdone originally well-intended (but often badly executed) intervention in the Middle East & Mesopotamia, and the European members have failed to meet their promises, to the others. Some initiatives have begun to correct both, but success is still far away. Despite that, dangers to the Freedom and safety of Europe still persist. They, in addition to the evident weakening of the fabric of the EU, are a risky combination.
I persist in believing that the authoritarian and bureaucratic approach the EU has taken to achieve the poorly described goal of "ever closer union" was an error: a more clearly stated federal approach, involving clear limits on the powers of the Central EU government would have achieved better results, and would likely have given the member states more flexibility in dealing with the several serious external issues that have arisen during the past two decades.
