Earlier quoted context omitted.
Would you prefer a strong, centralised EU government with a strong leader (aka dictator)? Well, I don't. But this is the only way to take direct action - as the individual members are not of a single mind.
Democracies can be capable of quick direct action too. See U.S. esp. U.S. some 50-70 years back. Democracy is no excuse for being inefficient, if democracies don't find a way to protect their values and interests, they will eventually be replaced by more efficient states
Much that the USA was or did 50-70 years ago was decidedly not democratic and not their proudest moment.
