That the TTIP-like deals take years is not by accident, but by design: the nasty stuff is to be included in one big package and obscured, to be accepted "by the democracy" only because it's a part of the whole "and look, there's some pork there too." Otherwise the smaller deals, which would actually be in the clear interest of both sides would happen much more often.
