Nah - the guy talks a lot. Difference is that he also follows up on it.
talking and barking are very different. barking is constantly making threats your ass can't cash where you said it so many times you start looking like the Chinese, with the whole "chinese final warnings".
for example when erdogan says "we can come suddenly one night" it has no effect whatsoever, no one takes it seriously. He said it too many times and done nothing.
