Of course the Americans have been involved in keeping outside threats outside.
But can you imaging Germany invading France through Belgium? Or Italy invading Greece? There has been peace between member states. And their solidarity keeps trouble away, outside the EU borders.
Which is not to say that Ukraine was not a major feck up.
Thats not because of the EU, though.
For a start, everyone who matters is in NATO anyway, so they are all allied to each other and would be if they weren't in the EU. Secondly, so massive was the US (and a not inconsiderable UK) military presence during the Cold War that most of the EU states didn't spend the amounts on their military that they used to, and so the armies that the French, Germans and the rest used to have no longer exist.
Finally there is the point that the EU, at least in its current state, is far more vulnerable than comparative states like the US, Russia or the Chinese are. It has no unified military. Its border security still boils down to individual states, specifically the least well off individual states who have strong incentives not to hold people at / on the border. The political class running the show is composed of most nations B and C teams, at best. There is no effective central authority, and the most powerful nations still acts in their own interests. There is very little, if any, ability for the citizens to change things politically and the Parliament provides no oversight at all.
I am a pro-European, but we should certainly leave unless the EU very quickly indicates what ever closer union is going to look like, and when it is going to be delivered. At present, we have a worse system than we would have if the EU were all separate nations; this cannot continue.
