Mousse You may have a high nerd quotient but you know sod all about the military. There is no way that military decisions can be democratic once troops are committed, be it on the ground, in the air, or at sea. The CO issues an order and it's obeyed, end of. Hopefully, that order is serving the general strategy laid out, but even the best ORBAT may not survive the first engagement.
I would argue that Article 5 isn't as binding as the Acquis, as it is not subject to a Court imposing it, and the NAC has to agree that the Article 5 conditions have been met. We can withdraw from the North Atlantic Treaty any time we choose, without all the crap associated with leaving the EU.
Given that the U.S. has been bankrolling the defence of Europe for 70 years next year, don't you think that a little influence, and indeed, thanks, are in order? There is no credible defence of Europe without NATO and the troops, materiel, money and nuclear umbrella supplied to NATO by the US
Peregrina NATO works and has been proven to do so. There is no military action without unanimity at the NAC, and the Perm Reps,and Mil Reps who sit on the NAC are taking instruction from their governments. I am against an EU set of Forces ( no point in an Army without a Navy or Air Force), as it duplicates NATO efforts, and there is no point. An EU set of Forces answerable to, paid by, and loyal to the EU, as opposed to NATO forces, seconded by their governments, are very different things. If you can't see that the former is what PESCO is about, then you have blinkers on. The UK has always been opposed to the EU having its own Forces, not least because UK Forces are Crown servants. Bit of a conflict when you have to swear allegiance to the EU and abjure your national loyalties ( and yes, UK military officers seconded to the EU Military Staff have to do that).
FYI, DSACEUR is a permanent Brit post whilst COS is German.
NATO had no mandate to intervene in Kosovo from the UN, despite seeking a Security Council Resolution as China and Russia blocked it. I think NATO was dampened either way; non intervention would have lead to more ethnic cleansing and international condemnation, and intervening wasn't going to be popular either. The EU hardly prevented the civil war either, so no point blaming NATO.
NATO intervention in Afghanistan was at the request and under the aegis of, the UN in the form of ISAF. Many non NATO nations also aided ISAF with money as well as troops. If you Google the list, it's interesting.
Putin's Russia is rearming and investing in its military. He has tried asymmetric warfare in the Crimea, and is eyeing up the Baltic States. Sweden and Finland are both twitchy at present. Latvia, Lithuania and Estonia are on edge. That is where, imo, Article 5 will be triggered. Putin will try to take back his near abroad and extend his sphere of influence in little bites. He will use Syria as a huge base once all the fighting is done.
