None of the EU countries do military interventions whatsoever. They'll lend some minor support to US lead NATO operations or the UN peace corps.
Yeah, the Dutch navy was fighting Somalian pirates, but it's not like we'll overthrow evil regimes.
No, I thought you were talking about how the EU handled (or rather: failed to handle) the refugee crisis.
For a while, most of the efforts (if any) were aimed at keeping the refugees outside our territorial waters, which was really shameful, especially when refugees started drowning by the hundreds a day.
See, the problem is: Europe is a big place, and we just couldn't agree on the policies. and what policies we did agree upon were largely ignored by the countries in the Southeast, who just couldn't handle the numbers of people flooding in, so they closed their borders, against all agreements. The results, of course, major humanitarian crisis, people literally dying in the mud outside the fences.
Merkel at least did the right thing, showing leadership, saying we could handle this.
But then Erdogan came along, and we made a deal with the devil. Now Turkey's limiting the influx of refugees, and he's bribing his way into the EU. Or so he dreams. But yeah, he does have the EU hostage now. He's already made several threats to open the borders again.
The only good thing I can say about the EU policies is that screening has become better, which means actual war refugees should be able to come, while we send the people away who come from countries that are safe.
